Abstract

A corona generating device generally comprises a shield having a coronode wire mounted therein. The coronode wire is generally operated from a filtered DC or DC biased AC power supply. It has been found that by exciting the coronode wire from a short duty cycle pulsed DC power supply, charge uniformity on a photoconductive surface is improved. Shield current can be reduced by using a resistor for biasing the shield.
