Abstract:
A process cartridge attachable to and detachable from an electrophotographic image forming apparatus includes a first unit having an electrophotographic photosensitive member, and a second unit including a developing roller configured to develop a latent image formed on the electrophotographic photosensitive member, and a sheet member which is disposed along the developing roller in a lengthwise direction of the developing roller and contacts the electrophotographic photosensitive member to restrain scattering of developer, wherein a contact portion of the sheet member that contacts the electrophotographic photosensitive member is roughened by a roughening process.
