Abstract
An electrophotographic photoreceptor comprises an electrically conductive substrate, a layer of charge generating material which chloroaluminium phthalocyanine and chloroaluminium monochlorophthalocyanine are evaporated in a vacuum over the electrically conductive substrate and the evaporated film of chloroaluminium phthalocyanine and chloroaluminium monochlorophthalocyanine are treated by an organic solvent selected from the group consisting tetrohydrofurane, methanol, acetone, methyl ethyl ketone, .alpha.-chloronaphthalene, pyridine, a layer of charge transport material overcoated the layer of charge generating material. The electrophotographic photoreceptor and the preparation thereof is disclosed to apply for use in a laser printing machine in which a light of laser diode or light emission diode is used as a light source. The solvent treated layer of evaporated film of chloroaluminium phthalocyanine and chloroaluminium monochlorophthalocyanine are observed to have a high photosensitivity in near infrared region, especially over 750 nM of wavelength regions.
