An object of the invention is to obtain an electrophotographic photoreceptor having high sensitivity, high image quality, high stability and high resolution. A charge generating layer of the electrophotographic photoreceptor contains, as a charge generating substance, a crystalline titanyl phthalocyanine composition exhibiting, in an X-ray diffraction spectrum of a CuK&agr; characteristic X-ray (wavelength: 1.5418 Å), at least four diffraction peaks at Bragg angles (2&thgr;±0.2°) of 10.0° or lower, and a diffraction peak at a Bragg angle of 27.2° having an intensity smaller than the maximum diffraction intensity of the four diffraction peaks, or a lowly crystalline titanyl phthalocyanine composition exhibiting a diffraction peak having the maximum diffraction intensity at a Bragg angle (2&thgr;±0.2°) of 27.3°. A charge transporting layer of the electrophotographic photoreceptor contains, as a charge transporting substance, a bisamine compound.
