To provide an image forming device capable of preventing a service life of a electrophotographic photoreceptor from being remarkably limited owing to a damage, the wear or the like, and restraining a problem such as the image flowing from occurring caused by a foreign matter such as a static discharge product material, or a paper powder (talk) shifted from a paper sheet.

In the image forming device forming the image, adopting the electrophotographic photoreceptor, through the cycle of electrifying, developing and transferring, the wear of a surface layer of the electrophotographic photoreceptor by using 1K cycle is 0.1 to 0.2nm. As an instance of preferable shape is, on the periphery of the electrophotographic photoreceptor 11, electrifying means 12, exposing means 13, toner developing means 14 and transferring means 15 is respectively arranged corresponding to processing stages, and at least the electrifying means 12, and the transferring means 15 is severally separated from the electrophotographic photoreceptor 11.
