    • Disclosed are a phthalocyanine composition suitable for use in an electrophotographic photoreceptor that exhibits a high charge potential and a high sensitivity and which exhibits stable performances without causing a change in various properties in repeated use, a process for the production thereof, and an electrophotographic photoreceptor to which the above phthalocyanine composition is applied. The present invention provides a phthalocyanine composition comprising a oxytitanium phthalocyanine and a metal-free phthalocyanine and having a crystal form having peaks at Bragg angles (2&thgr;±0.2°) of 7.0°, 9.0°, 14.1°, 18.0°, 23.7° and 27.3°, and having no peak at a Bragg angle (2&thgr;±0.2°) of 9.5°, in CuK&agr; 1.541-angstrom X ray diffraction spectrum, a process for the production of the above phthalocyanine composition, comprising carrying out crystal transformation treatment of an amorphous oxytitanium phthalocyanine and an amorphous metal-free phthalocyanine in a solvent containing water and a naphthalene, and an electrophotographic photoreceptor comprising an electrically conductive substrate and a photosensitive layer formed thereon, the photosensitive layer containing the above phthalocyanine composition as a charge-generating material.
