ABSTRACT:
An electrophotographic photoreceptor having a light-sensitive layer on an electroconductive base is disclosed, the improvement wherein the light-sensitive layer is formed from a dispersion in which a titanyl phthalocyanine pigment having at least two predominant peaks of the Bragg angle 2.theta. at 9.6.degree..+-.0.2.degree. and 27.2.degree..+-.0.2.degree. in a diffraction spectrum obtained with characteristic x-rays of Cu K.alpha. at a wavelength of 1.54 .ANG. is dispersed in a dispersion medium that contains at least one of branched ester and alcohol solvents as a chief component.
