An object of the invention is to improve the photosensitivity characteristics, characteristics on repeated use and stability of a photoreceptor. A photosensitive layer formed on a conductive support of a photoreceptor contains crystalline oxotitanylphthalocyanine having major peaks in an X-ray diffraction spectrum at Bragg angles (2&thgr;±0.2°) of 7.3°, 9.4°, 9.6°, 11.6°, 13.3°, 17,9°, 24.1° and 27.2°, wherein a peak bundle formed by overlapping the peaks at 9.4° and 9.6° is the largest peak, and the peak at 27.2° is the secondary largest peak as a charge generating substance. Furthermore, it contains a bisamine compound, an N,N′-bisenamine compound, a styryl compound, an amine-hydrazone compound, a benzofuran-bishydrazone compound, a bisenamine compound, a benzofuran-bishydrazone compound or a benzofuran-bis-cyclic hydrazone compound represented by the particular structural formulae as a charge transporting substance.
