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.
An electrophotographic single color copy process comprising the steps of applying an electrostatic charge onto the face of a receptor formed of a substrate having on its face a single 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, exposing the charged receptor to an original whereby portions of the photoconductive coating corresponding to the non-imaged areas of the original are discharged leaving a latent electrostatic image on the receptor, developing the exposed receptor with a developing composition containing a toner in the form of a material which, when in an activated state, is a solvent for the dispersed dye or an adhesive for the coating whereby toner is retained on the coating in areas retaining the electrostatic charge, and bringing a copy sheet in surface contact with the coating containing toner on the face thereof in a fluid state to cause transfer of the dispersed dye from the areas retaining the latent electrostatic charge to corresponding areas of the copy sheet.
