ABSTRACT:
An electrophotographic process of forming a dye image comprising the steps of:
(1) charging a photosensitive element formed on an electroconductive support by electrical charging, said photosensitive element consisting essentially of photoconductive particles and sublimable dyes, (2) exposing the charged photosensitive element to a light image, (3) developing the photosensitive element with acidic toners, (4) heating the photosensitive element to sublime the sublimable dyes, and (5) transferring the dye images to a dye-image accepting substrate with the aid of solvents.
An electrophotographic material comprising an electroconductive support and a photosensitive element (i.e., photoconductive layer) formed thereon, said photosensitive element consisting essentially of photoconductive powders and sublimable dyes.
