Intermediate transfer member for use in electrophotographic image forming apparatus
Abstract:
An intermediate transfer member is provided which enables to maintain superior secondary transferability and enhanced cleaning capability and is also capable of continuing to obtain toner images of superior text reproduction and high quality without causing lack of text images even when making prints of a large number of sheets (e.g., 160,000 sheets). The intermediate transfer member for use in an image forming apparatus having a device capable of transferring a toner image carried on the surface of an electrophotographic photoreceptor primarily to an intermediate transfer member, and secondarily transferring the toner image from the intermediate transfer member to a transfer material, wherein the intermediate transfer member is provided with an elastic layer on the circumference of a resin substrate and further thereon a surface layer, the surface layer exhibits a layer thickness of 10 to 500 nm, the Young's modulus of the surface of the intermediate transfer member which is determined by a nanoindentation method is 0.1 to 5.0 GPa and is 0.0 to 2.0 GPa greater than the Young's modulus of the elastic layer which is determined by a nanoindentation method.
