Electrophotographic photoreceptor with titanyl phthaloycyanine

An electrophotographic photoreceptor comprising a conductive substrate having provided thereon a photosensitive layer, said photosensitive layer comprising;

• a titanylphthalocyanine having a maximum peak, in the Cu-K.alpha. X-ray diffraction spectrum thereof, at a Bragg angle 2.theta. of 27.2.degree..+-.0.2.degree.,
• an alkyldiol compound having 3 to 12 carbon atoms and 2 hydroxyl groups, each hydroxyl group being bonded to a different, non-adjacent carbon atom, said alkyldiol compound being present in an amount of 0.1 to 1000 parts per 100 parts by weight of said titanylphthalocyanine, and
• a binder resin selected from the group consisting of polycarbonate, polycarbonate Z, acrylic resin, methacrylic resin, polyvinyl chloride, polyvinylidene chloride, polystyrene, styrene-butadiene copolymer, polyvinyl acetate, polyvinylformal, polyvinylbutyral, polyvinylacetal, polyvinylcarbazole, styrene-alkyd resin, silicone resin, silicone-alkyd resin, silicone-butyral resin, polyester, polyurethane, polyamide, epoxy resin, phenolic resin, vinylidene chloride-acrylonitrile copolymer, vinyl chloride-vinyl acetate copolymer and vinyl chloride-vinyl acetate-maleic anhydride copolymer.
