PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which can meet demands involved in a size reduction and an increased speed of copying machines and printers, that is, demands for a reduction in diameter of photoreceptor and a high-peripheral speed process, and at the same time, which has high sensitivity even in a long wavelength range, is free from a deterioration in electric characteristics even after repeated use, and is highly stable. SOLUTION: The electrophotographic photoreceptor comprises an electroconductive support and a photosensitive layer comprising at least a charge generating agent, a charge transfer agent and a binder resin stacked on the electroconductive support. The electrophotographic photoreceptor is characterized in that: the charge generating agent is oxytitanium phthalocyanine and the oxytitanium phthalocyanine shows a maximum peak at 27.2°Bragg angle (2θ±0.2°) in an X-ray diffraction spectrum using CuKαas a radiation source; and the charge transfer agent contains a compound represented by formula (1).
