<P>PROBLEM TO BE SOLVED: To provide a semiconductive belt which can be cleaned with a blade without inversion or squeaking to remove a toner remaining on a surface after transfer, and ensures little degradation of surface performance even by contact with a wet toner or an oil-component-containing toner, with respect to a semiconductive belt used as an intermediate transfer belt or the like in an electrophotographic apparatus. <P>SOLUTION: A surface layer of the semiconductive belt for an electrophotographic apparatus has a tensile modulus of elasticity of 150-180 MPa, an elongation after fracture of 250-500%, and a trailing contact angle of ≥10° to a 9-14C unsaturated hydrocarbon solvent in a dynamic wetting test, and a coating agent forming the surface layer contains (1) a copolymer of a fluorine modified acrylate and another acrylate, (2) a fluorinated olefin, and (3) a copolymer of methyl methacrylate and another monomer having a (meth)acryloyl group. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
