A new process of graphic reproduction and photography has been developed. The basic process, known as xerography, is dry, direct positive-to-positive, rapid, and has a number of potential applications in graphic arts and related fields. As a photographic process, xerography employs a re-usable plate consisting of a thin layer of a photo-conductive material on an electrically conductive base. The plate is sensitized by electrostatic charging immediately before use. After exposure, the image is developed by dusting the plate with a micronized powder. Prints are made by transferring and fixing the powder image to paper or other materials. The plate can be used many times to produce additional images. Xerography also provides a unique and simplified process of graphic reproduction, particularly in printing and duplicating.
