Abstract
A transfer charging device is arranged with dual transfer-assist blades consisting of a pressure blade and a halo blade. The pressure blade is arranged for contacting and thereby urging a substrate against an image-bearing photoreceptor. The pressure blade is formed of a relatively conductive material. The halo blade is formed of a dielectric material. The halo blade is positioned between the transfer charging device and the pressure blade to shield the pressure blade from being charged-up by the transfer charging device.
