PROBLEM TO BE SOLVED: To provide an image forming device that a good image is output even under a condition that a carrier phenomenon is easily generated. SOLUTION: Relating to the image forming device provided with a developer carrier carrying a two-component developer while rotational speed and applied voltage are controlled and a photoreceptor forming a toner image using toner fed from the developer carrier while surface potential is controlled, it is characterized by that at least one of the rotational speed of the developer carrier, a DC component of the applied voltage or the surface potential of the photoreceptor is varied. |
