intermediate transfer bodies

Abstract

An excellent intermediate transfer member which, even when used for printing on a plurality of sheets, does not crack to thereby cause image defects and can retain satisfactory cleaning ability without suffering toner filming, and with which high-quality printed images free from fog caused by toner filming are continuously obtained. The intermediate transfer member is for use in an image-forming device having a means of first transferring a toner image deposited on the surface of an electrophotographic photoreceptor to an intermediate transfer member and then secondly transferring the toner image from the intermediate transfer member to a receiving material. The intermediate transfer member comprises a resin base, and formed on the periphery thereof, an elastic layer and a surface layer, the surface layer being composed of an interlayer and a rigid layer, the interlayer being a layer having a lower hardness and a lower modulus than the rigid layer.

Description

technical field [0001] The present invention relates to intermediate transfer bodies. Specifically, it relates to an intermediate transfer body used in electrophotographic image formation, the intermediate transfer body provided with at least a surface layer on an elastic layer. Background technique [0002] Currently, in electrophotographic image formation, when transferring a toner image formed on the surface of an electrophotographic photoreceptor (hereinafter simply referred to as photoreceptor) to a transfer material such as paper, in addition to transferring the toner image from the photoreceptor In addition to the method of directly transferring the surface of the body onto the transfer material, there is also a method of using a belt-shaped or roll-shaped member called an intermediate transfer body. This method includes primary transfer for forming a toner image from an electrophotographic photoreceptor to an intermediate transfer body and secondary transfer for tra...

AI Technical Summary

Problems solved by technology

Otherwise, the surface of the intermediate transfer body cannot maintain its shape due to abrasion during transfer

Therefore, the technologies disclosed in the above-mentioned patent documents all take into account the problem that the transferability is reduced due to the existence of the elastic layer, and in order to further improve the durability, other layers such as an inorganic coating are placed on the elastic layer.
