プロセスカートリッジ
Document Type and Number:
Japanese Patent JP7094781
Kind Code:
B2
Abstract:
To sufficiently improve wear resistance to prevent an increase in torque and an increase in temperature caused by rubbing between a cleaning blade and a photoreceptor associated with an increase in speed/elongation of a life.SOLUTION: In a process cartridge, a toner has a Martens hardness of 200 MPa or more and 1100 MPa or less when the toner is measured under a condition of a maximum load of 2.0×10N, and a protective layer of an electrophotographic photoreceptor has a Martens hardness of 200 MPa or more and 280 MPa or less.SELECTED DRAWING: None
