Abstract

PURPOSE: To obtain a sufficient cleaning effect by the multiplied force of a mechanical wiping force and an electric attracting force by providing a winding type wiping member and by applying the opposite polarity to the polarity of the residual toner from the back of the wiping member.
CONSTITUTION: A wiping member 8 has its end portions held at a delivery roller 10 and a take-up roller 11 so that a new portion can always be delivered. The wiping member 8 is supplied with a voltage at its back from an electrode 12 and is forced into contact with the recording drum 1 by a pressure member 14 made of an elastic material, which is interposed between itself and a holding member 13 for holding the electrode 12, so that the toner left on the recording drum 1 is mechanically wiped off by the wiping member 8 and is removed by the electrostatic attraction which is generated by the voltage application by an electrode portion 9.
