Abstract

Dicorotron devices have been used to perform negative charging functions in an electrophotographic environment. A corona wire is coated with a dielectric material and excited by an AC voltage capacitively coupled to the air across the dielectric sheaths. A net DC current to the surface to be charged is obtained by applying a DC bias to the surrounding corona shield.
