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 1):
An image forming apparatus comprising:\n an endless transfer belt that travels while carrying a toner image on a transfer surface thereof; a cleaning device that sweeps off toner remaining on the 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 rotation direction of the transfer belt from the cleaning device; and a support member that supports the pre-cleaning brush from a side opposite to a side of the transfer belt, wherein the support member has a support wall that extends over approximately the whole in a width direction of the transfer belt while facing the transfer surface of the transfer belt and supports the pre-cleaning brush, and the support wall is formed with openings that liberate foreign matters including toner deposited onto the pre-cleaning brush.
