摘要

Apparatus (10) and method for forming an electrostatic latent image on an imaging member (14) having a photoconductive insulation layer (15), has a voltage-sensitive coronacharging device (50) with a corona-generating electrode and a control electrode positioned in charging relationship to the photoconductive insulation layer, means for energizing the charging device to charge the photoconductive insulation layer to a first level, comprising means for applying a corona-generating voltage to the corona-generating electrode and for applying a control voltage of a first magnitude to the control electrode, and means for exposing the photoconductive insulation layer to an image pattern of discharging radiation concurrent with the charging device being energized.
