For example, azo pigments such as Sudan Red, Guianpuru, Jenas Green B, quinone pigments such as Algol Yellow, Pyrenequinone, Indanthrene Brilliant, and Violet RRP, quinocyanine pigments, indigo pigments such as Indigo and Thioindigo, and Indian Examples include bishenzimidazur pigments such as Fast Orange, phthalocyanine pigments such as copper phthalocyanine, and quinacridone pigments such as quinacridone. These pigments are used at a relatively high concentration (0.1 to 0.9 weight ratio in the solid substance) in the functionally separated type, and at a relatively low concentration (0.01 to 0.5 weight ratio in the solid substance) in the single layer type. ) and dispersed in an organic binder to form a charge generation layer or photoreceptor. Examples of the organic binder that can be used here include polyester, polyvinyl butyral, polycarbonate, polystyrene, polyvinyl chloride, methyl cellulose, acrylic resin, and organic polysilane.
