PURPOSE:To enhance resistances to printing and humidity by forming a photoconductive layer prepared by dispersing a phthalocyanine type photoconductor powder coated with a electrostatic charge transfer material and/or an antioxidant or allowed to absorb them into a binder resin. CONSTITUTION:The photoconductive layer is formed by dispersing a phthalocyanine type photoconductor powder coated with the charge transfer material and the antioxidant allowed to absorb them into the binder resin, resulting in remarkably enhancing deterioration preventive effect on such a treated photoconductor. The coating material prepared by mixing such a treated photoconductor with the binder resin has a good viscosity, such as low viscosity and low tendency to structural viscocity, and good storage stability due to no agglomeration tendency. The electrophotographic sensitive body obtained by using it has good electrophotographic characteristics, such as photosensitivity, repetition durability, humidity resistance, and printing resistance. |
