ABSTRACT:
A photoreceptor for use in a two color electrostatic imaging process is disclosed which comprises a conductive substrate layer; a first photogenerating layer overlaying the substrate layer which is sensitive to a first wavelength; a unipolar hole transporting layer overlaying the first photogenerating layer; and a second photogenerating layer overlaying the hole transporting layer which is sensitive to a second wavelength and at least partially transmits the first wavelength; wherein the transporting layer is substantially transparent to the first wavelength.
An apparatus for forming multi-color images of an object employing the photoreceptor of the invention, wherein the color images are properly registered with respect to each other, is also disclosed.
