Abstract
A process cartridge is provided for detachably mounting to a main assembly of an electrophotographic image forming apparatus. 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, and 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. The process cartridge also includes a force receiving member capable of taking an operating position for moving the developing frame from the contacting position to the spacing position by receiving an external force, and a stand-by position retracted from the operating position.
