ABSTRACT:
An improved corona generating device for an electrostatic reproduction machine having a photoreceptor has a discharge electrode, a conductive shield partially surrounding the electrode, and a cleaning member in contact with and mounted for movement along both the electrode and shield. The improvement lies (1) in the mechanism for moving the cleaning member along the device, this mechanism including a dielectric member located between the electrode and shield so as to increase the corona to the photoreceptor, and (2) in the cleaning member, this member including material impregnated with an abrasive.
