PROBLEM TO BE SOLVED: To provide an image forming device with which a stable image without having a change in image density and gradation is always formed even in the case of adopting a DC contact electrifying system by DC voltage fixed at a specified value and a DC contact developing system by the fixed DC voltage. SOLUTION: In the image forming device A, the DC voltage applied to an electrifying means 2 and DC voltage applied to a developing means 23 are respectively fixed at specified values, and a storing means 26 stores information with respect to the film thickness of the photoreceptor 1, and the exposure of an exposing means 3 is controlled by the information with respect to the film thickness of the photoreceptor 1. |
