Abstract: A method and apparatus for transferring a latent electrical image from a photosensitive image receptor to a dielectric or insulating image receptor where the photosensitive image receptor comprises a conductive base, a photoconductive layer arranged on it and on top of it a protective layer of transparent, insulating and non-photoconductive material. The protective layer surface is charged in the dark to a specific first potential; the photoconductive layer is image-exposed thereafter; the insulating image receptor is placed on the protective layer and a second, lower potential applied on the free surface of the insulating image receptor; and the insulating image receptor is separated from the protective layer of the photosensitive image receptor.
