Intermediae transfer member, and its using image forming method and image forming device

Abstract

It is an object to provide an intermediate transfer member that maintains a good second transferability and a good cleaning property even when print is repeatedly carried out and continuously obtains a high quality tonner image without the occurrence of a non-printing portion of a character image, and an image forming method and a image forming device that use the intermediate transfer member. The intermediate transfer member is used for an image forming device provided with a means which, after the tonner image carried on a surface of a photosensitive member is first transferred to the intermediate transfer member, the tonner image is second transferred to a transfer member. The intermediate transfer member is characterized in that including an inorganic layer on the most outer surface, wherein the inorganic layer defines a contact angle of 30 DEG -60 DEG with respect to methylene iodide and the hardness of the inorganic layer measured by a nanoindentation method is in the range of 3GPa-10GPa.

Description

technical field [0001] The present invention relates to an intermediate transfer body, an image forming method using the intermediate transfer body, and an image forming apparatus. Background technique [0002] Conventionally, an image forming method using an intermediate transfer body is known as a method of transferring a toner image carried on the surface of an electrophotographic photoreceptor (hereinafter also simply referred to as a photoreceptor) onto a transfer material. In this image forming method, the toner image is first transferred from the electrophotographic photoreceptor to the intermediate transfer body, and then the toner image is secondarily transferred from the intermediate transfer body to the transfer material to obtain the final image. This method is a multi-transfer method in which a color-decomposed original image is reproduced by subtractive mixing of toners such as black, cyan, magenta, and yellow. The toner images are sequentially transferred fr...

AI Technical Summary

Problems solved by technology

[0007] However, in the intermediate transfer body described in Patent Document 1, since the surface energy of the intermediate transfer body is low, aggregation of toner tends to occur, and therefore there is a problem of frequent hollowing.

In addition, according to the intermediate transfer body described in Patent Document 2, in the case of continuous printing (for example, 100,000 sheets), the cleaning performance of the remaining toner is reduced, and the surface of the intermediate transfer body is contaminated with toner or the like (toner or the like). Toner filming), there is a problem of poor image quality after transfer
