Abstract
An image forming apparatus includes a photosensitive member, a charging device, an exposure device, a development device, a transfer device, a first driving device, a voltage application device, and a controller. The first driving device rotatably drives one of the photosensitive member and a combination of the photosensitive member and an intermediate transfer member. The voltage application device supplies a respective predetermined voltage to the charging device, the development device, and the transfer device. The controller controls the first driving device and the voltage application device. When the photosensitive member is stopped, both illumination from the exposure device and the transfer electrical field electrically discharge the surface of the photosensitive member.
