IMAGE FORMING APPARATUS

摘要

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.

1. An image forming apparatus, comprising:
a photosensitive member to bear an electrostatic latent image on a surface thereof; a charging device to apply a charging bias to the surface of the photosensitive member to uniformly charge the surface thereof; an exposure device to illuminate the surface of the photosensitive member to form the electrostatic latent image, the exposure device being disposed downstream from the charging device in a direction of rotation of the photosensitive member; a development device to develop with a development bias the electrostatic latent image using a development agent to form a toner image, the development device being disposed downstream from the exposure device in the direction of rotation of the photosensitive member; a transfer device to transfer the toner image from the photosensitive member onto one of an intermediate transfer member and a recording medium by a transfer electrical field, the transfer device being disposed downstream from the development device in the direction of rotation of the photosensitive member; a first driving device to rotatably drive one of the photosensitive member and a combination of the photosensitive member and the intermediate transfer member; a voltage application device to supply a respective predetermined voltage to the charging device, the development device, and the transfer device; and a controller to control the first driving device and the voltage application device, both illumination from the exposure device and the transfer electrical field discharging the surface of the photosensitive member when the photosensitive member is stopped.
