Abstract:
1. An image forming apparatus comprising: image bearing member; a charging member for charging said image bearing member by applying a voltage; charge voltage applying means for applying a voltage to said charging member, wherein a remaining voltage on the image bearing member attenuates after a supply of the voltage from said charge voltage applying means to said charging member is turned off; electrostatic latent image forming means for forming an electrostatic latent image on said image bearing member charged by said charging member; a developing member for forming a visible image on the basis of the electrostatic latent image formed on said image bearing member; developing voltage applying means for applying a voltage to said developing member; and electric potential controlling means for switching the voltage to be applied to the developing member in a plurality of steps in response to an attenuation state of the attenuation region.
