PURPOSE:To improve the electrical characteristics of an electrophotographic sensitive body obtd. by successively forming an intermediate layer contg. fine particles of an org. pigment dispersed in an insulating resin and a photoconductive layer of an Se compound on an electrically conductive support by using a specified disazo pigment as the org. pigment. CONSTITUTION:An intermediate layer contg. fine particles of an org. pigment dispersed in an insulating resin and a photoconductive layer of an Se compound are successively formed on an electrically conductive support. At this time, a disazo pigment represented by formula I [where A is a group represented by formula II, III or IV (where each of X and Ar1-Ar3 is an aromatic ring or the like, and each of R1 and R3 is H, lower alkyl or the like)] is used as the org. pigment. The electrically conductive support is made of a metal such as Al or Ni, the oxide thereof, synthetic paper coated with the metal or metallic oxide, or the like. Since the intermediate layer consists essentially of the insulating resin and the disazo pigment represented by the formula I , the adhesive property of the photoconductive layer to the support and the electrical characteristics can be improved. |
