    Abstract: A photoreceptor for an image formation apparatus has a photosensitive layer of a multi-layer structure each having the characteristic of increasing its electrical resistance at a different rate upon expose to light. An image-carrying beam of reflected light from an original to be copied is made incident on the photoreceptor to form a resistance image. An electrostatic latent image is formed therefrom either on the photoreceptor itself or on a transfer medium placed in contact therewith and a visible toner image is formed by applying toner on such an electrostatic image but the resistance image on the photoreceptor remains undisturbed during such image transfer processes. Thus, a plurality of copies of a single original can be produced without exposing the photoreceptor to reflected light therefrom for each copy to be printed.
