Abstract
A charging system for a reproduction machine is provided comprising a photoreceptor member having the property of dark injecting only a single side of mobile carrier from an injection layer; an alternating current voltage source operating at a frequency f; and a bias roller charging member electrically connected to the alternating current voltage source and comprised of a deformable conductive material supported in deforming engagement with the photoreceptor member during relative movement of the photoreceptor and the bias roller charging member. The bias roller is maintained in contact with any given area on the photoreceptor for a period greater than or equal to 1/f the bias roller charging member to provide uniform charging and avoid strobing.
