CORONA CHARGING DEVICE

摘要

A flat scorotron device (200) includes pin electrodes (212) and a charge level control electrode (215) coplanar on the surface of an insulator (220). The pin electrodes are connected to a high voltage D.C. bus bar (205, 210) through a resistive material (230) and a relatively low voltage is applied to the electrode (215). A low watt heater (211) is attached to one surface of the insulator to negate the effects of high relative humidity environment on the device.
