Abstract

In electrophotography, wherein electrostatic charges are provided by corona wire apparatus for discharing a photoreceptor, a combined corona and luminescent discharge is provided in a single compact arrangement by connecting to the exposed corona wire, in addition to the conventional high potential for ionization, a high current, low voltage, power supply which heats the corona wire to above approximately 800 DEG Centigrade, making it self-luminously incandescent. Optical reflectors may be provided to further direct this light onto the photoreceptor. The wire temperature is maintained below white heat, and the wire material is selected, so as not to oxidize rapidly. Transformer or capacitor electrical isolation is provided to prevent interference between the two power supplies.
