  • Electrophotographic cleaning blade, process cartridge, and electrophotographic image forming apparatus
    Patent number: 11630411
    Abstract: The present invention is aimed at providing an electrophotographic cleaning blade that has excellent chipping resistance and can exhibit excellent cleaning performance. This cleaning blade is provided with an elastic member that includes a polyurethane and a support member that supports the elastic member, and cleans the surface of a member to be cleaned that is moving, by bringing a part of the elastic member into contact with the surface of the member to be cleaned. The average value of the elastic modulus of the elastic member obtained when measured using SPM is at least 15 MPa and not more than 470 MPa, and the coefficient of variation thereof is not more than 6.0%.
