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