Abstract
Primary charging of a moving electrographic photoconductor to a nominal potential level is achieved with low sensitivity to variation in system parameters, such as photoconductor capacitance, photoconductor velocity and/or charger efficiency. Separately-addressed, AC corona discharge units are arranged and predeterminedly biased to first substantially overcharge the photoconductor relative to the nominal potential and then discharge the photoconductor to exit at the nominal potential level.
