PURPOSE: To provide an image forming device capable of always obtaining the excellent image by preventing a failure such as deterioration in the image density or carrier adhesion from occurring, even in a bright side of an exposure step in the exposure adjustment. CONSTITUTION: In a light side of the exposure step input unit 25, at every time when the exposure step is switched in the light direction, control for lowering a surface potential of a photoreceptor drum 1, or for raising a developing bias voltage to the developing unit 4 is executed by increasing the applying voltage to the exposure lamp 10 at a specified little inclination, and reducing an electrification current to the electrification charger 2, corresponding to the exposure deficit. |
