Claims

[Claims for Utility Model Registration] (1) Applying a bias voltage to conductive bristles implanted on the circumferential surface of a cylindrical body, pressing and rotating the bristles to rub and remove residual toner on the surface of the image carrier. In a cleaning device consisting of a cleaning brush having a conductive cylindrical body and a collection roller having a conductive cylindrical body applied with a bias voltage and brought into contact with the cleaning brush and rotated to collect toner from the cleaning brush, when an image is formed, Other than that, the cleaning device is further provided with a release means that is controlled so that the cleaning brush and the collection roller are separated from each other. (2) The cleaning device according to claim 1, further comprising a release means that controls the cleaning brush and the image carrier to separate from each other except during image formation.
