Abstract:
A process cartridge detachably attachable to a main body of an electrophotographic image forming apparatus, comprising:an electrophotographic photosensitive drum; a developing member configured and positioned to develop an electrostatic latent image formed on said electrophotographic photosensitive drum with toner; a first frame configured and positioned to support said electrophotographic photosensitive drum; a second frame configured and positioned to support said developing member; a coupling pin configured and positioned to couple said first frame to said second frame to be rotatable relative to each other; a supporting portion, provided in said second frame, for engaging with said coupling pin so that said second frame is rotatable relative to said first frame; a hole into which said coupling pin is press-fitted and which is provided in said first frame; a closed portion provided in said hole to close a downstream side of said hole in a press-fit direction in which said coupling pin is press-fitted into said hole, and an air path configured to discharge air inside said hole to the outside of said hole when said coupling pin is press-fitted into said hole.
