PROBLEM TO BE SOLVED: To provide an image forming device where a photoreceptor can be used in a wide range of film thickness without any troublesome means such as correction of the quantity of exposure by having the dependency on the film thickness of potential after exposure of the photoreceptor to be kept down to a small range. SOLUTION: In the image forming device carrying out image formation by electrifying the photoreceptor, forming an electrostatic image by exposing and developing the electrostatic image, it is characteristic that surface potential of the photoreceptor before the exposure Vo is set so that the difference ΔVr of the potential of the photoreceptor after the exposure and the potential of the photoreceptor after the exposure in an initial period of use is <=50 volts. |
