Abstract
An article having improved electrostatic charge transfer properties. The improvement in charge transfer properties results from subjecting a layer of photoconductive-insulative material or dielectric material on the charge donor or a layer of dielectric material on the charge receptor, or both layers, to plasma treatment process to provide an oxygen-enriched surface to the photoconductive-insulative layer and/or the dielectric layer.
