Abstract: A cartridge includes a coupling member, a transmitted member, and a rotary member. The transmitted member includes an accommodating portion configured to accommodate the coupling member, and a protruded portion integrally formed with an inner wall of the accommodating portion and protruding from the inner wall toward an inside of the accommodating portion. The coupling member includes a free end portion having a rotational force receiving portion that receives a rotational force, a connected portion connected to the transmitted member in such a manner that at least a part of the connected portion can be accommodated in the accommodating portion, and a recessed portion provided at the connected portion so that the protruded portion can enter. An inclination angle of a rotation axis of the coupling member relative to a rotation axis of the transmitted member is variable.

Abstract: A substrate processing apparatus includes: a process chamber accommodating substrates; a heating system for heating the process chamber to a predetermined temperature; a precursor gas supply system including a precursor gas nozzle and for supplying a precursor gas from the precursor gas nozzle to the process chamber; a reaction gas supply system configured to supply a reaction gas reacting with the precursor gas in the process chamber; and a control part configured to control the heating system, the precursor gas supply system and the reaction gas supply system to form a film on each of the plurality of substrates by performing a process, while heating the process chamber accommodating the plurality of substrates to the predetermined temperature. The process includes supplying the precursor gas from the precursor gas nozzle to the process chamber and supplying the reaction gas to the process chamber.

Abstract: A packing member for packing a cartridge detachably mountable to an image forming apparatus is molded with a thin resin material plate and includes: (i) a frame portion including an opening as an entrance for the cartridge, a first recessed portion for accommodating the cartridge, and a first limiting portion for limiting a position of the cartridge with respect to a direction perpendicular to a longitudinal direction of the cartridge; and (ii) a cap portion for openably covering the opening. The cap portion includes a second limiting portion for limiting movement of the cartridge, positionally-limited by the first limiting portion, in a direction in which the cartridge is spaced from the first limiting portion.

Abstract: A packing member for packing a cartridge which is detachably mountable to an image forming apparatus includes: a frame portion including an opening as an entrance for the cartridge, a first recessed portion for accommodating the cartridge, and a limiting portion, provided in the first recessed portion, for limiting a position of the cartridge with respect to the direction crossing a limiting portion of the cartridge; and a cap portion, provided rotatably connected to the frame portion by a hinge portion, for openably covering the opening. The limiting portion limits the position of the cartridge so that the cartridge is located in a position where a grip portion of the cartridge is remoter from the hinge portion than the center line of the cartridge with respect to the crossing direction and a direction crossing an entering direction in which the cartridge enters the frame portion.

Abstract: A packing member for packing a cartridge detachably mountable to an image forming apparatus is molded with a thin resin material plate and includes: (i) a frame portion including an opening as an entrance for the cartridge, a first recessed portion for accommodating the cartridge, and a first limiting portion for limiting a position of the cartridge with respect to a direction perpendicular to a longitudinal direction of the cartridge; and (ii) a cap portion for openably covering the opening. The cap portion includes a second limiting portion for limiting movement of the cartridge, positionally-limited by the first limiting portion, in a direction in which the cartridge is spaced from the first limiting portion.

Abstract: A unit for use with an image forming apparatus includes: a frame; a developer accommodating portion; a sheet member, contact to a rotatable member and provided on the frame along a longitudinal direction of the rotatable member; a first end portion seal member for preventing, at a longitudinal end portion, the developer from leaking out from between the frame and the rotatable member; and a second end portion seal member for preventing the developer from leaking out from among the first end portion seal member, the sheet member and the frame. The second end portion seal member is formed by injecting, on the frame, a resin material having an elastic modulus smaller than an elastic modulus of the frame so as to contact with the first end portion seal member and the sheet member.

Abstract: A cleaning unit usable with an image forming apparatus includes a cleaning blade, supported by a frame and including a free end contactable to an image bearing drum, for removing a developer from the drum; a first seal provided between the frame and the blade by injection molding into the frame adjacent to a longitudinal end portion of the blade, the first seal being effective to prevent developer leakage; and a second seal provided between the drum and the frame in contact with the free end of the blade adjacent to the longitudinal end portion, wherein the first seal includes a seal portion contacting the blade, and a seat supporting the second seal, the seat being deformable to move the second seal to urge the second seal to the free end of the blade when the drum is mounted to the frame.
