装置。[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. , the rotational direction of the collection roller can be changed and controlled at any time, and the roller is rotated in a direction that prevents the conductive bristles of the brush from falling down relative to the rotational direction of the cleaning brush. cleaning equipment. (2) The cleaning device according to claim 1, wherein when the collection roller rotates while contacting the cleaning brush, the direction of rotation thereof changes periodically.
