Abstract:
1. 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, said process cartridge comprising: an electrophotographic photosensitive drum; a developing roller for developing an electrostatic latent image formed on said electrophotographic photosensitive drum; a drum unit containing said electrophotographic photosensitive drum; a developing unit which contains said developing roller and which is movable relative to said drum unit such that developing roller is movable between a contact position in which said developing roller is contacted to said electrophotographic photosensitive drum and a spaced position in which said developing roller is spaced from said 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 said 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 said first force receiving portion by a force received from the first force application member, wherein said second force receiving portion takes a projected position for receiving a force from the second force application member to move said developing unit from the contact position to the spaced position, the projected position being higher than the stand-by position.
