Patent ID: 7592112

Claim:
A multilayer electrophotographic photoreceptor comprising: an electroconductive substrate, and at least an interlayer and a charge-generating layer formed on the substrate, wherein the interlayer comprises a binder resin containing at least one of alizarin and an alizarin derivative, in which fine metal oxide particles are dispersed, and that has a volume resistivity in a range of 1.0×10 8 Ω·cm to 1.0×10 13 Ω·cm when an electric field of 10 6 V/m is applied thereto at 28° C. and 85% relative humidity; and wherein the charge-generating layer comprises an anthraquinone derivative wherein the anthraquinone derivative contained in the charge-generating layer is the same as the alizarin or alizarin derivative contained in the interlayer.
