Abstract:
1. An electrophotographic photoreceptor comprising: an electroconductive substrate; a first charge generation layer overlying the electroconductive substrate and configured to generate a first charge to form an electrostatic latent image when exposed to a first light, said first charge generation layer including a first charge generation material; a charge transport layer overlying the first charge generation layer; and a second charge generation layer overlying the charge transport layer and configured to generate a second charge when exposed to a second light, said second charge generation layer including a second charge generation material, wherein the charge transport layer transports the first charge to the second charge generation layer, and the first charge generation layer is configured to have a first sensitivity to a first wavelength of light greater than 700 nm and the second charge generation layer is configured to have a second sensitivity to a second wavelength of light less than 600 nm.
