Abstract
An electrophotographic photoreceptor includes a conductive substrate and a photosensitive layer including a charge generation material and a charge transport material. The charge generation material is a titanyloxyphthalocyanine crystal having a maximum diffraction intensity observed at Bragg angle (2.theta.) of 9.6.degree..+-.0.2.degree. and clear peaks of diffraction intensity observed at 7.22.degree..+-.0.2.degree., 9.60.degree..+-.0.2.degree., 11.60.degree..+-.0.2.degree., 13.40.degree..+-.0.2.degree., 14.88.degree..+-.0.2.degree., 18.34.degree..+-.0.2.degree., 23.62.degree..+-.0.2.degree., 24.14.degree..+-.0.2.degree., and 27.32.degree..+-.0.2.degree., respectively, in a X-ray diffraction spectrum obtained by performing a X-ray diffraction method using CuK.alpha. as a source of radiation, and having a lattice constant of: EQU a=16.3058 .ANG., b=23.078 .ANG., and c=8.7115 .ANG., EQU .alpha.=101.352.degree., .beta.=23.078.degree., and .gamma.=117.530.degree. , with an allowable error of .+-.1%.
