PURPOSE: To provide a cleaning device for eliminating particles from an image carrier surface and an electric grounding line body formed along its end area.

CONSTITUTION: A brush ring or a brush doughnut 120 made of an insulating (non-conductive) material is attached to the end part of an electrostatic brush cleaner 100 for eliminating charged toner or other residuals from the surface 11 of a photoreceptor 10 and the remaining particles of a grounding line 130 are cleaned. This brush ring or doughnut 120 is superposed on the grounding line 10 and had a width slightly overlapped with the surface 11 of the photoreceptor 10. Thus, the possibility of contact between a conductive cleaner brush fiber and the grounding line 130 is eliminated and toner on the grounding line 130 which causes base (background) staining of a print or a copy is effectively and efficiently cleaned.
