Abstract:
An image forming apparatus, comprising:a photosensitive member that holds an image formed by a developing agent; a scanner unit that scans a laser beam on a surface of the photosensitive member in order to from the image onto the photosensitive member; a charging device that is disposed along the surface of the photosensitive member upstream, along a rotating direction of the photosensitive member, from a scanning area where the laser beam is scanned on the surface and that charges the surface of the photosensitive member; a voltage applying device that applies a voltage to the charging device; a first cleaning element that is disposed along the surface of the photosensitive member upstream, along the rotating direction of the photosensitive member, from the charging device and that contacts the surface of the photosensitive member, wherein the charging device is between the first cleaning element and the scanning area along the surface of the photosensitive member; a second cleaning element that contacts a surface of the first cleaning member; and a first voltage controlling device, connected to the charging device, the first cleaning element and the second cleaning element, that generates a predetermined potential difference between the first cleaning element and the second cleaning element based on the voltage applied to the charging device.
