Abstract
An image forming apparatus executes reverse charging, toner-supply suspension, second exposure, and second charging, while a photosensitive member rotates at least a full turn. In the reverse charging, a charger charges a portion of a circumferential surface of the photosensitive member to a specified polarity. In the toner-supply suspension, before the portion, which has been charged to the second polarity in the reverse charging, of the circumferential surface of the photosensitive member passes a position at which the developer from the developing unit is configured to initially adhered to the circumferential surface, a developing unit stops supplying developer to the circumferential surface. In the second exposure, an exposure device exposes the portion, which has been charged to the specified polarity in the reverse charging, of the circumferential surface. In the second charging the charger charges the portion, which has been exposed in the second exposure, of the circumferential surface.
