Abstract: A toner container for containing toner has a container main body portion, a container end portion, an aperture portion, and an extendable portion connecting the container main body portion and the container end portion. The extendable portion renders the portion capable of a relative rocking motion. The toner is discharged from the aperture portion by the relative rocking motion of the container main body portion and the container end portion.

Abstract: A toner supply container detachably mountable to a main assembly of an electrophotographic image forming apparatus includes (a) a toner accommodating portion for accommodating toner; (b) a toner supply opening for discharging toner accommodated in the toner accommodating portion; (c) a toner feeding member having a toner feeding portion for feeding the toner accommodated in the toner accommodating portion toward the toner supply opening by rotation thereof and an extension extending from the toner feeding portion, wherein a center of rotation of the toner feeding member is in an opening region of the toner supply port as seen in the longitudinal direction of the toner feeding member and wherein the toner feeding member penetrates through the toner supply opening so that the extension is rotatably supported and driven.

Abstract: A developer cartridge includes a cylindrical body for accommodating a developer with a discharge opening, provided in a cylindrical portion of the cylindrical body, for permitting discharge of the developer. A sealing member seals the discharge opening. A stirring member is provided in the cylindrical body and includes a shaft for receiving a driving force to rotate the stirring member and elastic stirring blades provided on the shaft. The stirring blades have free end portions bent in a radial direction.

Abstract: A toner supply container detachably mountable to a main assembly of an electrophotographic image forming apparatus includes (a) a toner accommodating portion for accommodating toner; (b) a toner supply opening for discharging toner accommodated in the toner accommodating portion; (c) a toner feeding member for feeding the toner accommodated in the toner accommodating portion toward the toner supply opening; (d) a sealing member including: a sealing portion for openably sealing the toner supply opening; and a driving portion for driving the toner feeding member.

Abstract: A developer cartridge comprising a cylindrical portion for accommodating a developer, being provided with a hole at a longitudinal end, wherein the developer is capable of being supplied into the cylindrical portion through the hole, a removable cap for capping the hole, and a gripping member for covering the cap and having a plate-like grip. A developing remanufacturing method, wherein the cartridge includes a cylindrical portion having an opening extending in a longitudinal direction, the cylindrical portion being provided with a hole at a longitudinal end, a cap for capping the hole and a gripping member, includes the steps of removing the gripping member, removing the cap, sealing the opening, supplying a developer through the hole, capping the hole, and mounting the gripping member.

Abstract: In the present process for producing a toner, previous to the melt-kneading process, the binder resin particles and colorant particles are mixed and treated to application of shear, compression and impact forces to fasten, or fix, the colorant particles to the binder resin particles.

Abstract: A pneumatic pulverizer comprises an accelerating tube for carrying and accelerating powder to be pulverized with high-pressure gas and a pulverizing chamber for pulverizing the powder to be pulverized. The back end of the accelerating tube is provided with a pulverization powder feed port for feeding powder to be pulverized to the accelerating tube, the pulverizing chamber has an impact member having an impact surface opposed to the opening plane of the outlet of the accelerating tube, the and a side wall against which the powder to be pulverized that has been pulverized by the impact member collides to further pulverize.

Abstract: A developer container includes a container portion having an opening through which developer is supplied in or out; a shutter member for opening and closing the opening; a slide-guide for guiding the shutter member; a recess on a surface of the slide guide on which the shutter member slides.

Abstract: A developer cartridge detachably mountable to a developing apparatus having a shutter for closing and opening a developer receiving opening, includes a cylindrical portion for accommodating a developer, the cylindrical portion being provided with an opening extending along a length thereof; a sealing member for sealing the opening; a first projection for moving the shutter to an open position for the developer receiving opening in interrelation with rotation of the developer cartridge in a first direction; and a second projection for moving the shutter to a close position for the developer receiving opening in interrelation with rotation of the developer cartridge in a second direction which is opposite from the first direction.

Abstract: A pneumatic pulverizer comprises an accelerating tube for carrying and accelerating powder to be pulverized with high-pressure gas and a pulverizing chamber for pulverizing the powder to be pulverized. The back end of the accelerating tube is provided with a pulverization powder feed port for feeding powder to be pulverized to the accelerating tube, the pulverizing chamber has an impact member having an impact surface opposed to the opening plane of the outlet of the accelerating tube, and a side wall against which the powder to be pulverized that has been pulverized by the impact member collides to further pulverize. The closest distance from the side wall to a margin of the impact member is shorter than the closest distance from the front wall of the pulverizing chamber opposed to the impact surface to the margin of the impact member to prevent pulverized powder from fusing, coagulating, and getting coarser, and prevent localized abrasion of an impact surface the impact member and the accelerating tube.

Abstract: A pneumatic pulverizer includes an accelerating tube for conveying and accelerating a material to be pulverlized by a high-pressure gas and a pulverizing chamber for finely pulverizing the material to be pulverized. The pulverizing chamber is provided with a colliding member having a colliding surface provided in opposed relation to an outlet of the accelerating tube. The colliding surface of the colliding member has a protruding central portion, and an outer peripheral colliding surface provided around the protruding central portion for secondarily pulverizing the material primarily pulverized by the protruding central portion. The pulverizing chamber has a side wall for performing tertiary pulverization on the material secondarily pulverized by the outer peripheral colliding surface.
