ABSTRACT:
The invention disclosed relates to an apparatus for removing residual toner from a surface to be cleaned which has a rotatable cleaning brush in frictional engagement with the surface, a dusting bar disposed in abutting relation to brush bristles of the cleaning brush for dusting toner off said brush bristles, both of said dusting bar and said brush bristles being made of electrically conductive material with at least one covered with an insulating material, and means for forming an alternating electric field between the brush bristles and the dusting bar. By this, residual toner is effectively removed from the brush bristles to prevent occurrence of the filming phenomenon.
