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.
(ZH) 提供电子照相感光体，随着复写机、印刷机装置的小型化、高速化，该感光体能够满足感光体的小径化、线速度快的工艺的要求，并且在长波长区具有高灵敏度，即使反复使用电特性也不会劣化，而且稳定性高。该电子照相感光体是在导电性支撑体上层合至少含有电荷产生剂、电荷转移剂和粘合树脂的感光层而形成，该感光体的特征在于：该电荷产生剂为酞菁氧钛，该酞菁氧钛在以CuKα为射线源的X射线衍射图谱中在布拉格角(2θ±0.2°)27.2°处有最大峰，上述电荷转移剂含有下式表示的化合物。
