摘要：
A cleaning blade for removing fine particles from a cleaning target by contact with the cleaning target, a method of using the cleaning blade, and an image forming apparatus and process cartridge using the cleaning blade. The cleaning blade includes an elastic blade. A leading edge of the elastic blade includes a friction coefficient of 0.5 or less. The cleaning blade also includes a surface layer that covers the leading edge of the elastic blade. A thickness of the surface layer is between 1 to 50 μm at a position 50 μm away from the leading edge, and a hardness of the surface layer is greater hardness than the elastic blade.
