Abstract: A toner container includes a vessel for storing toner, a toner draining unit having a toner draining passage, and a shutter in the toner draining passage. The toner draining passage includes a horizontal passage and a connection passage. Further, the toner draining unit includes the horizontal passage, a middle part, and an external part.

Abstract: A developing device of the present invention develops a latent image formed on an image carrier with a two-ingredient type developer made up of toner and carrier. The developing device includes a storing member for storing a fresh developer to be replenished. A conveying device conveys the fresh developer from the storing member to a case, which stores the two-ingredient type developer to be deposited on the image carrier, while fluidizing the fresh developer. An excess developer discharging portion is configured to discharge excess part of the two-ingredient type developer to the outside. The developer storing member is implemented as an at least partly flexible bag.

Abstract: A toner container includes a storing body that stores toner, a toner reception opening that receives the toner from the toner storing body, a shutter opening, a cylindrical shutter, and an O-shaped elastic ring disposed at the shutter opening configured to seal a space between the shutter opening and the shutter. The shutter receives a nozzle of an image forming apparatus and the cylindrical shutter opens and closes the shutter opening when moved by a nozzle of the image forming apparatus inserted into the shutter opening. When the nozzle is disposed through the shutter opening, the toner which is received from the toner reception opening is subsequently received by the nozzle of the image forming apparatus.

Abstract: A developer container storing a developer of the present invention includes a developer outlet formed in the side wall thereof, and a shutter member for selectively opening or closing the developer outlet. The shutter member opens the developer outlet when the developer container is mounted to the body of an image forming apparatus or closes it when the former is dismounted from the latter. The toner container with this configuration surely prevents the developer from leaking when the developer container is dismounted from an image forming apparatus.

Abstract: A part of a toner supply path is formed in a setting unit (100), and a nozzle (110) coupled to a toner container (20) is provided, wherein the fitting direction of the toner container (20) to the setting unit (100) and the coupling direction of the nozzle (110) to the toner container (20) are different.

Abstract: The body member of a powder container of the present invention includes a bag-like powder storing body storing powder and formed with an opening at one end, and a base member affixed to the opening of the powder storing body. The base member allows an outlet member, which is formed with a passage configured to deliver the powder from the powder storing body to an outlet and has a shutter function for selectively blocking or unblocking the passage, to be connected to or disconnected from the base member.

Abstract: A powder container for use in an image forming apparatus. The powder container includes a powder storage section, a dispenser, a shutter, and a closing mechanism. The dispenser has an opening which faces horizontally and is oriented to receive a horizontal nozzle. The shutter is horizontally disposed within the dispenser and is movable by a nozzle of the image forming apparatus. The closing mechanism is arranged to receive a force when the nozzle is removed from the opening and when the powder container is disconnected from the image forming apparatus.

Abstract: A developer container storing a developer of the present invention includes a developer outlet formed in the side wall thereof, and a shutter member for selectively opening or closing the developer outlet. The shutter member opens the developer outlet when the developer container is mounted to the body of an image forming apparatus or closes it when the former is dismounted from the latter. The toner container with this configuration surely prevents the developer from leaking when the developer container is dismounted from an image forming apparatus.

Abstract: A toner for forming a visual image on an image bearer having a maximum shearing stress of about 30 G (N/m2) when a maximum shearing stress test is performed using a uniaxial collapsing stress measuring method and a vertical stress 16 G (N/m2) is applied. Alternatively the toner has a uniaxial collapsing stress of about 50 G (N/m2).

Abstract: A part of a toner supply path is formed in a setting unit, and a nozzle coupled to a toner container is provided, wherein the fitting direction of the toner container to the setting unit and the coupling direction of the nozzle to the toner container are different. There is a powder container having an upper section and a multi-part lower section. The multi-part lower section has an upper portion and a lower portion, the lower portion having an opening which is perpendicular to an opening of the upper portion. The upper and lower portions are rotatably engaged such that the upper portion and the lower portion are engaged with each other when rotated to a first position relative to each other, and the upper portion and the lower portion are unengaged with each other when rotated to a second position relative to each other.
