PURPOSE:To obtain a high-sensitivity electrophotographic sensitive body even if a phenolic layer dispersed with carbon is used as a conductive base layer by providing an insulating layer on the phenolic resin layer dispersed with carbon and providing a layer dispersed with a pigment on the insulating layer. CONSTITUTION:The insulating layer is provided on the phenolic resin layer dispersed with the carbon and the layer dispersed with the pigment is provided on said insulating layer. The phenolic resin which has <=10<8>OMEGA, more particularly <=10<5>OMEGA electric resistance on the surface is preferable as the phenolic resin dispersed with the carbon. There is no particular limitation as the material to form the insulating layer, for which various org. high-polymer compds. are usable; for example, synthetic high polymers such as PP resin, acrylic resin, polyimide resin and polysilastyrene and natural high polymers such as casein, starch and cellulose or the modified matters thereof are used. Water soluble natural high polymers or the moldified polymers thereof are more preferable above all. The preferred thickness of the insulating layer is usually 0.01-3mu. The good electrophotographic sensitive body is thereby formed. |
