Abstract:
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, the transfer device including, 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 second driving device to rotatably drive the intermediate transfer member and the first driving device that drives the photosensitive 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, wherein
