Abstract: A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.

Abstract: A process cartridge includes a force receiving member that is provided movably relative to a developing frame. The force receiving member includes a spacing force receiving portion configured to receive a spacing force for moving a developing roller when the force receiving member is in a projected position, and a retracting force receiving portion configured to receive a retracting force for moving the force receiving member toward a retracted position when the force receiving member is in the projected position. The retracting force receiving portion has a surface slanted with respect to the direction in which the spacing force receiving portion is capable of receiving the spacing force.
