Abstract:
1. A process cartridge detachably mountable to a main assembly of an image forming apparatus, comprising: a photosensitive member unit including an electrophotographic photosensitive member; and a developing unit including a developing roller for carrying developer so as to develop a latent image formed on the electrophotographic photosensitive member and a sheet member which contacts the electrophotographic photosensitive member at one lateral end thereof and is fixed to said developing unit at the other lateral end thereof, said developing unit being swingable with respect to said photosensitive member unit so as to establish contact and separation between the developing roller and the electrophotographic photosensitive member, wherein when the developing roller is separated from the electrophotographic photosensitive member, a first contact portion provided to said developing unit and a second contact portion provided to said photosensitive member unit contact each other so as to prevent separation of the sheet member from the electrophotographic photosensitive member.
