Abstract
An apparatus for producing identification cards including a photograph of a person and written material by using electrostatic and transfer printing techniques. A photoreceptor comprising a layer of photoconductive material on a conductive supporter is charged and is exposed to an optical image of a person to form an electrostatic latent image of the person on the photoconductive material layer. An identification card material comprising a layer of dielectric material on a conductive supporter is placed on top of the photoreceptor to transfer print the electrostatic latent image from the photoreceptor to the identification card material. Toner particles are then supplied to the dielectric material layer of the identification card material to develop the electrostatic latent image thereon into a visible image. Written matter may then be entered on the identification card material, and the identification card material may be protected by lamination.
