Abstract
This invention is addressed to a single color electrophotographic copy process in which a receptor having a photoconductive coating comprising a photoconductor, at least one sensitizer which sensitizes the photoconductor to at least a portion of the spectrum of visible light, a binder and a dispersed dye on the face thereof is charged and exposed to an original whereby the portion of the photoconductive coating corresponding to the non-imaged areas of the original are discharged leaving a latent electrostatic image on the receptor and then the exposed receptor is developed with a toner in the form of a material which, when in an activated state acts as a solvent or adhesive for the dispersed dye in the photoconductive coating for transfer of the dye color in the photoconductive coating in response to surface contact of the developed receptor with a copy sheet.
