Electrophotographic blade, process cartridge, and electrophotographic image forming apparatus
Abstract:
An electrophotographic blade to be brought into contact with a contact member, comprises a plate spring, and a resin layer that covers at least a part of a surface of the plate spring to form a contact region that comes into contact with a contact member. In the state where one of ends of the plate spring is fixed, a length (L) from the fixed end to the another end is 5 mm to 20 mm, and a force needed to displace the another end by 1 mm is 5 N/m to 100 N/m. The resin layer satisfies the requirements: (1) the thickness of the resin layer is 0.05 mm to 2.00 mm, (2) the tan δ value of the resin layer in the range of 5° C. to 40° C. is 0.05 to 0.70, and (3) the elastic modulus of the resin layer is 1.0 to 60.0 MPa.
