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

Claim (Index 15):
A control method to be executed by a controller of an image forming apparatus, the image forming apparatus configured to perform a printing process on a recording medium, the printing process including a first charging, a first exposure, and a toner supplying in which toner is supplied from a developing unit to a photosensitive member of the image forming apparatus, the photosensitive member having a photosensitive layer, the control method comprising:\n second charging while the photosensitive member rotates at least a full turn, the second charging including controlling a charger of the image forming apparatus to charge a portion of a circumferential surface of a photosensitive member of the image forming apparatus in a period different from an execution period of the first charging, wherein the charger is configured to charge the circumferential surface of the photosensitive member to generate a first electric field in a corresponding portion of the photosensitive layer; second exposure while the photosensitive member rotates at least a full turn, the second exposure including controlling an exposure device, having a light source, to expose the portion, which has been charged in the second charging, of the circumferential surface of the photosensitive member; toner-supply suspension before the portion, which has been exposed in the second exposure, of the photosensitive member passes a position at which developer from the developing unit is configured to initially adhere to the circumferential surface of the photosensitive member, the toner-supply suspension including controlling a developing unit of the image forming apparatus to stop supplying the developer to the photosensitive member; and second-electric-field generation while the photosensitive member rotates at least a full turn, the second electric-field generating including controlling an electric circuit of the image forming apparatus to apply a voltage to generate, in conjunction with an electric field generating member, a second electric field in the corresponding portion of the photosensitive layer when the portion, which has been charged in the second charging and subsequently exposed in the second exposure, of the circumferential surface of the photosensitive member reaches a position facing the electric field generating member, wherein the second electric field is directed in a direction opposite to the first electric field.
