Title
(EN) Electrophotographic photoreceptor and electrophotographic apparatus
(ZH) 电子照相感光体和电子照相装置
Abstract
(EN) 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, is highly stabile. 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 (2theta + 0.2 DEG) providing a maximumpeak at 27.2 DEG in the X-ray diffraction spectra using CuKalpha as a radiation source. The electron charge-transfer agent includes a compound represented by the following formula.
