Abstract
A device for depositing charge on a charge retentive surface including an insulative support substrate coated with a layer of highly resistive material and a high voltage bus coupled thereto for providing a high voltage potential across the resistive material layer. The resistive charging device is positioned in contact with or in close proximity to a charge retentive surface to provide a uniform charging potential for depositing ions onto the charge retentive surface.
