PROBLEM TO BE SOLVED: To provide a color image forming device adopting an a-Si (amorphous silicone) photoreceptor capable of realizing the increase of speed, the extension of a life and the reduction of a cost. SOLUTION: This color image forming device is allowed to perform control for changing charge potential on a charging roller 10 so that the surface potential on the a-Si photoreceptor 2 becomes the specific potential when respectively reaching developing device for developing of developing means 3Y, 3M, 3C, and 3B by providing the charging roller 10, exposing means 11, respective developing device 3Y, 3M, 3C, and 3B on the a-Si photoreceptor 2 periphery, and making an exposure quantity of the exposing means 11 specific. |
