Abstract:
1. An image forming apparatus comprising: an image carrier rotating and having an electrostatic latent image formed by exposure of a charged surface of said image carrier to light and developed with developer charged to a predetermined polarity; a charging member charging said image carrier; a developing member arranged on a downstream side in a rotational direction of said image carrier with respect to said charging member for attaching said developer onto said image carrier to develop the formed electrostatic latent image; a supplying member supplying said developer to said developing member; an electrostatic removing unit neutralizing a potential on said surface of said image carrier; a developing member voltage application unit applying a voltage to said developing member; a supplying member voltage application unit applying a voltage to said supplying member; an electrostatic removing unit voltage application unit applying an electrostatic removing unit voltage to said electrostatic removing unit; and a voltage application control unit controlling the voltage applied to said developing member by said developing member voltage application unit, the voltage applied to said supplying member by said supplying member voltage application unit, and the voltage applied to said electrostatic removing unit by said electrostatic removing unit voltage application unit, wherein where a voltage applied to said charging member from a charging member voltage application unit is changed, said voltage application control unit controls said electrostatic removing unit voltage application unit not to apply the electrostatic removing unit voltage to said electrostatic removing unit.
