Abstract

An image forming apparatus includes a charging member for charging a surface of a photosensitive member to a first potential, an exposing member for partially exposing the charged surface of the photosensitive member such that a potential of the exposed portions becomes a second potential smaller than the first potential, a developer carrier for feeding developer onto the photosensitive member, a discharging-beam member for irradiating a discharging beam onto the photosensitive member having a developer image, and a control device configured to: control a developing bias to become a third potential larger than the second potential and smaller than the first potential; and control a discharging bias such that a potential of portions on the photosensitive member where the developer image has not been formed becomes a fourth potential not smaller than the third potential and smaller than the first potential.
