Abstract

The control corona generating device for use in electrostatographic copiers usually comprises an elongated metallic channel member with three sides, a center rib, and an open end along which two corotron wires are extended. Generally, these devices are relatively long, for example, up to 16 inches, and have been found to produce less photoreceptor current at the ends than at the center. The resultant lower charge voltage produces non-uniform darkness within a copy.
