An electroconductive endless-belt of tandem system circulatorily for transfer and/or conveyance which is circulatorily driven by a drive unit, and which conveys a recording medium retained on the belt by electrostatic attraction to four kinds of image formation members, and sequentially transfers each toner image onto the recording medium, characterized in that the endless belt comprises as a base material, at lease one member selected from the group consisting of acrylonitrile-styrene resin containing 3 to 50 mass % of a flexible component having glass transition temperature lower than 25° C., a polymer alloy of thermo plastic resin with acrylonitrile-styrene resin containing 3 to 50 mass % of a flexible component having glass transition temperature lower than 25° C., and a polymer blend of thermo plastic resin with acrylonitrile-styrene resin containing 3 to 50 mass % of a flexible component having glass transition temperature lower than 25° C., and an image formation apparatus equipped with the endless-belt. The belt is excellent in strength, folding endurance, creep durability and dimensional stability.
An electroconductive endless-belt of tandem system for transfer and/or conveyance, which is circulatorily driven by a drive unit, and which conveys a recording medium retained on the belt by electrostatic attraction to four kinds of image formation members, and sequentially transfers each toner image onto the recording medium, characterized in that the endless belt comprises as a base material, at least one member selected from the group consisting of acrylonitrile-styrene resin containing 3 to 50 mass % of a flexible component having glass transition temperature lower than 25° C., a polymer alloy of a thermoplastic resin with acrylonitrile-styrene resin containing 3 to 50 mass % of a flexible component having glass transition temperature lower than 25° C., and a polymer blend of a thermoplastic resin with acrylonitrile-styrene resin containing 3 to 50 mass % of a flexible component having glass transition temperature lower than 25° C.
An electroconductive endless-belt which is used for an intermediate transfer member, is located between an image formation body and a recording medium, and is circulatorily driven with a drive unit, thereby once transferring and retaining, on the surface of itself, a toner image formed on the surface of the image formation body, and then transferring the image thereon onto the recording medium, characterized in that the endless-belt comprises as a base material, at least one member selected from the group consisting of acrylonitrile-styrene resin containing 3 to 50 mass % of a flexible component having glass transition temperature lower than 25° C., a polymer alloy of a thermoplastic resin with acrylonitrile-styrene resin containing 3 to 50 mass % of a flexible component having glass transition temperature lower than 25° C., and a polymer blend of a thermoplastic resin with acrylonitrile-styrene resin containing 3 to 50 mass % of a flexible component having glass transition temperature lower than 25° C.
