Abstract:
A process cartridge detachably mountable to an electrophotographic image forming apparatus main body, includes: an electrophotographic photosensitive drum; a process member for acting on the electrophotographic photosensitive drum; a frame for holding the electrophotographic photosensitive drum; convex portions, which are provided coaxially with an axis of the electrophotographic photosensitive drum and protrude from one side and from the other side of the frame, for positioning the process cartridge in the apparatus main body when the process cartridge is mounted to the apparatus main body, and a concave portion provided in the upper part of the frame and recessed in the one side, in which the concave portion allows the process cartridge to be inserted into the apparatus main body without abutting against a protrusion provided in the apparatus main body in an inserting process of the process cartridge.
