<p>An image forming apparatus includes a photosensitive member, a charging device for electrically charging the photosensitive member, an electrostatic image forming portion for forming an electrostatic image on the photosensitive member, and a developing device including a toner carrying member and a screw. In addition, a charging power source applies a charge potential to the charging device, a developing power source applies a developing potential to the developing device, a transfer device transfers a toner image formed on the photosensitive member, and an exposure device electrically discharges a surface of the photosensitive member by exposing it to light. A controller controls the exposure device so that an exposure operation is in an off state in the period in which a toner feeding operation is performed or so that an exposure amount of the exposure device in the period in which the toner feeding operation is performed is smaller than an exposure amount of the exposure device in a period in which the toner image is formed on the surface of the photosensitive member.</p> |
