Patent ID: 7622232

Claim:
An electrophotographic photoreceptor comprising: an electrically conductive substrate; and a photosensitive layer formed on the electrically conductive substrate, wherein the photosensitive layer comprises a titanyl phthalocyanine crystal having a major absorption peak at a wavelength of 780 nm±10 nm and a minor absorption peak having an intensity of ¾ or less of the major absorption peak at 690 nm±10 nm in the visible-infrared absorption spectrum and a distyryl compound represented by Formula 1 below: where at least one hydrogen atom of the phenyl and the phenylene group can be substituted with a C 1 -C 6 alkyl group or a C 1 -C 6 alkoxy group, wherein the titanyl phthalocyanine crystal does not have an absorption peak at a wavelength of 800 nm or greater in the visible-infrared absorption spectrum and has a distinct peak at a Bragg angle (2θ) of 9.2°, 14.5°, 18.1°, 24.1°, and 27.3° (all may include an error of ±0.2°) in an X-ray diffraction spectrum.
