Claims

[Claims for Utility Model Registration] (1) A bias voltage is applied to a rotatable conductive bristles, and the conductive bristles are rubbed against an image carrier to form a residue on the surface of the image carrier. A cleaning device for an image forming apparatus, comprising a cleaning brush that removes toner, and a collection roller that applies a bias voltage to a rotatable conductive roller and brings it into contact with the cleaning brush to collect toner from the cleaning brush. 2. A cleaning device, characterized in that the surface of the conductive member constituting the collection roller is provided with an insulating layer made of a material whose triboelectric charging property is opposite in polarity to that of the toner. (2) The cleaning device according to claim 1, wherein the conductive member constituting the collection roller is made of metal. (3) The cleaning device according to claim 1 or 2, wherein the insulating layer provided on the surface of the conductive member is made of resin.
