Abstract
An electrophotographic photoreceptor which can respond to a reduction in diameter of photoreceptor and a process having high circumferential speed, due to the demand in the miniaturization and increase in the speed of copiers and printers. The photoreceptor has high sensitivity in long-wavelength region, and is free from deterioration of electric characteristics even after repeated use, and is highly stable. The electrophotographic photoreceptor has a conductive support member and a photosensitive layer laminated thereon, which includes at least a charge-generating agent, a charge-transfer agent, and a binder resin. The charge-generating agent is oxytitanium phthalocyanine, which has a Bragg angle (2θ±0.2°) providing a maximum peak at 27.2° in the X-ray diffraction spectra using CuKα as a radiation source.
