    摘要: A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, the main assembly including an opening, a door movable between a close position for closing the opening and an open position for opening the opening, a first force application member movable with movement of the door from the open position to the closing position and a second force application member movable by a driving force from a driving source, the process cartridge includes an electrophotographic photosensitive drum; a developing roller for developing an electrostatic latent image formed on the electrophotographic photosensitive drum; a drum unit containing the electrophotographic photosensitive drum; a developing unit which contains the developing roller and which is movable relative to the drum unit such that developing roller is movable between a contact position in which the developing roller is contacted to the electrophotographic photosensitive drum and a spaced position in which the developing roller is spaced from the electrophotographic photosensitive drum; and a force receiving device including a first force receiving portion for receiving a force from the first force application member by movement of the door from the open position to the close position in the state that process cartridge is mounted to the main assembly of the apparatus through the opening, and a second force receiving portion movable from a stand-by position by movement of the first force receiving portion by a force received from the first force application member, wherein the second force receiving portion takes a projected position for receiving a force from the second force application member to move the developing unit from the contact position to the spaced position, the projected position being higher than the stand-by position.

    摘要: An electrophotographic photosensitive drum usable with an electrophotographic image forming apparatus, includes a non-circular twisted projection (72a) having a cross-section with a plurality of corner portions, the non-circular twisted projection being provided at one longitudinal end of the electrophotographic photosensitive drum and being engageable with a non-circular twisted hole (73a) having a section with a plurality of corner portions, the non-circular twisted hole being disposed at a central portion of a driving rotatable member (73) of a main assembly of the image forming apparatus; and a second electroconductive member (71) contactable with a first electroconductive member (70) electrically connected with a main assembly of the image forming apparatus, the first electroconductive member being disposed in the hole to provide a grounding of the electrophotographic photosensitive drum, the second electroconductive member being provided on the projection and being electrically connected with the electrophotographic photosensitive drum. A contact position (b2) between the second electroconductive member and the first electroconductive member moves in interrelation with the projection being retracted toward the hole by rotation of the driving rotatable member when the twisted projection is engaged with the hole and rotates integrally with the projection when in use for driving the drum.
