Abstract:
An image forming apparatus includes a transfer belt, a cleaning device that sweeps off toner remaining on a transfer surface of the transfer belt by using a rotary brush, electrically adsorbs the toner swept by a recovery roller, and removes the toner, a pre-cleaning brush that slidably contacts with the transfer surface of the transfer belt at an upstream side in a belt rotation direction from the cleaning device, and a support member that supports the pre-cleaning brush. A support wall of the support member is formed with openings that liberate foreign matters such as toner and paper powder deposited onto the pre-cleaning brush.

Claim (Index 6):
The image forming apparatus of  claim 2 , wherein the pre-cleaning brush and the support member have conductivity, and\n the image forming apparatus further comprises: a voltage applying unit that applies a voltage having a predetermined polarity to the pre-cleaning brush via the support member; and a control unit that controls a polarity of a voltage to be applied by the voltage applying unit, wherein the control unit is configured to allow the polarity of the voltage to be applied by the voltage applying unit to differ in a part corresponding to an image formation area in the transfer belt and an inter-paper area.
