Electrophotographic member and electrophotographic image forming apparatus

An electrophotographic image forming apparatus comprising an electrophotographic member, wherein

• the electrophotographic member comprising:
• a base material;
• an elastic layer on the base material;
• and
• a surface layer on the elastic layer, wherein
• the elastic layer comprises silicone rubber,
• the surface layer comprises fluoro rubber,
• a thickness of the surface layer is 3 μm or more,
• an elastic deformation power ηIT calculated from a load displacement curve, obtained with a nanoindentation test according to ISO 14577 by bringing a Vickers indenter into contact with an outer surface of the surface layer and setting a test load at 120 μN, is 30 to 50%, and
• a Martens hardness determined by the nanoindentation test at the outer surface of the surface layer is 12.0 to 18.0 N/mm2.
