Abstract
A corona discharge device for electrophotographic printing is provided in which erasing and primary charging functions are performed by a single device. A screened charging arrangement is used for ion steering, while simultaneous illumination by light produces charge carriers in the photoconducting layer of the drum. In one embodiment, a photochemically etched stainless steel screen is used.
