摘要:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus includes a cartridge frame; an electrophotographic photosensitive member; process means actable on the photosensitive member; a first cartridge guiding portion for being guided by a main assembly guide provided in the main assembly of the apparatus when the process cartridge is mounted to the main assembly of the apparatus, the first cartridge guiding portion being provided at one end, with respect to a mounting direction in which the process cartridge is mounted to the main assembly of apparatus, of the cartridge frame; and a second cartridge guiding portion for being guided by the main assembly guide provided in the main assembly of the apparatus when the process cartridge is mounted to the main assembly of apparatus, the second cartridge guiding portion being provided at the other end, with respect to the mounting direction, of the cartridge frame, wherein when the process cartridge is mounted to the main assembly of the apparatus, the first and second cartridge guiding portions are at different heights.
摘要:
A recycling method for a developer supply unit (5) for supplying a developer to developing means (1) for developing an electrostatic latent image formed on an electrophotographic photosensitive member (2), wherein the developer supply unit (5) is detachably mountable to a main assembly of an electrophotographic image forming apparatus (100) and includes a developer accommodating portion (5j) for accommodating the developer, a developer supply port (5f) for supplying the developer to the developing means (1) and a feeding member (5a) for feeding the developer to the developer supply port (5f) from the developer accommodating portion (5j), the method includes an injection step of injecting the developer through the developer supply port (5f); and driving step of driving the feeding member (5a) in a direction (A-E) for feeding the developer from the developer supply port (5f) to the developer accommodating portion (5j), by which the developer is fed from the developer supply port (5f) to fill the developer accommodating portion (5j) with the developer.
摘要:
A developer supply container (12) for supplying a developer to a process cartridge (10) detachably mounted to an electrophotographic image forming apparatus (100), the process cartridge (10) containing an electrophotographic photosensitive drum (7) and a charging member (8) for charging the drum (7), the developer supply container (12) includes a developer accommodating portion (12k) for accommodating a developer; a developer supply opening (12f) for supplying the developer accommodated in the developer accommodating portion (12k) to the cartridge (10); a container closing member (12f3) movable between a closing position in which it closes the developer supply opening (12f1) and an open position in which it is retracted from the closing position to open the developer supply opening (12f); a first container guide (12g1) provided at one end with respect to a longitudinal direction of the along the longitudinal direction of the developer supply container (12), the first container guide (12g1) being capable of being guided by a main assembly guide (20) provided in the apparatus (100); a second container guide (12g2) provided at the other end with respect to a direction crossing with the longitudinal direction along the longitudinal direction of the developer supply container (12), second container guide (12g2) being capable of being guided by the main assembly guide (20) provided in the apparatus; container force receiving portion (12f3c) for receiving, a force for opening the supply opening (12f1) by movement of the closing member (12f3) from the closing position to the opening position by engagement with a cartridge engaging portion (10e4) provided in the cartridge (10) mounted to the apparatus (100); and a first container positioning portion (12r2), provided at a leading end, the first container positioning portion (12r2) being engageable with a first main assembly positioning portion (22b) provided in the apparatus (100), wherein the developer supply container (12), when it is mounted to the main assembly of the apparatus (100), the first container positioning portion (12r2) is positioned by the first main assembly positioning portion (22b), and the developer supply container (12) is positioned relative to the apparatus (100) by the first container guide and the second container guide (12g1,12g2) being supported by the main assembly guide (20) at a trailing edge side with respect to the mounting direction.
