Patent ID: 8396389

Claim:
An image forming apparatus comprising: a belt including an abutting surface, said abutting surface having a mirror surface smoothness of 40 to 200 and a pensile hardness of 2H to 7H, or having the mirror surface smoothness of 60 to 200 and the pensile hardness equal to or greater than H and less than 2H; and a cleaning blade disposed to abut against the abutting surface for removing a substance on the abutting surface, wherein said belt includes a surface layer having the abutting surface and a base layer covered with the surface layer and formed of at least one resin layer, said surface layer has a thickness between 1 μm and 10 μm, and said cleaning blade is formed of a urethane rubber having a rubber hardness of 60 to 90° , a breaking elongation of 250 to 500%, and a modulus of repulsion elasticity of 10 to 70%, said cleaning blade being arranged to contact with the belt with a line pressure of 1 to 6 g/mm.
