A process cartridge detachably mountable to a main assembly of an image forming apparatus includes an electrophotographic photosensitive drum (1); a developing roller (4A) for developing an electrostatic latent image formed on the electrophotographic photosensitive drum with a developer; a first frame supporting the electrophotographic photosensitive drum; a second frame supporting the developing roller; a coupling member for coupling the first frame and the second frame such that developing roller and the electrophotographic photosensitive drum are contacted to each other or are spaced from each other; an urging member (50) for urging the electrophotographic photosensitive drum and the developing roller toward each other; a spacer member (60) for keeping a state in which the electrophotographic photosensitive drum and the developing roller are spaced from each other or in which a distance between centers of the electrophotographic photosensitive drum and the developing roller is larger than a distance therebetween during image forming operation; wherein the spacer member supports the first frame and second frame at least at longitudinally extending surfaces of the process cartridge, and is detachable from the process cartridge. |
