摘要： A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes an electrophotographic photosensitive drum, a developing roller, a drum frame, a movable developing frame taking a position where the roller contacts the drum, and a force receiver having first and second force receivers for receiving first and second external forces. The second force receiver moves relative to the developing frame. The second force receiver takes a stand-by position retracted from an operating position when the first force receiver receives the first external force, and moves from the stand-by to the operating position for moving the developing frame from the contacting position to the spacing position. The distance the second force receiver moves from the stand-by to the operating position is larger than the distance the first force receiver moves by the first external force.
