ABSTRACT:
A corona discharge device including a corona discharge electrode and a conductive shield located adjacent the electrode, the electrode being coated with relatively thick dielectric material so as to substantially prevent the flow of conduction current therethrough. The delivery of charge to the photoconductive surface is accomplished by means of a displacement current or capacitative coupling through the dielectric material. The flow of charge to the surface to be charged is regulated by means of a d.c. bias applied to the corona shield.
