Process cartridge and electrophotographic image forming apparatus
First Claim
1. A process cartridge configured to be detachably attachable to a main body of an electrophotographic image forming apparatus, the process cartridge comprising:
- an electrophotographic photosensitive member and a cleaning member arranged in contact with the electrophotographic photosensitive member, whereinan elastic deformation modulus of a surface layer of the electrophotographic photosensitive member is 35% or larger, andthe cleaning member is formed of a urethane foam, said urethane foam having a density of 200 to 500 kg/m3 and a 25% compressive load of 0.3 MPa or smaller.
