PURPOSE:To enhance the mechanical life and durability of a photosensitive body by forming an interlayer made of a specified material between a photosensitive layer and a protective layer. CONSTITUTION:The electrophotographic sensitive body is formed by successively laminating on a conductive substrate 4 a photosensitive layer 3, the interlayer 2 made of an organometallic complex, such as a silyl isocyanate material, alkoxy-containing silicone resin, or Zr-acetylacetone, a mixture of the organometallic complex and a silane coupling agent, or an inorganic material, such as a silicon compound of a-SiC or the like, or a boron compound, such as a-BN, and the protective layer 1. The interlayer 2 has a volume resistivity rho, a ratio of a forward current J per unit volume to an applied electric field E of a photosensitive body, and a ratio of forward current to reverse current I1/I2, each satisfying the following expressions: 10<12>OMEGA.cm<=rho<10<14>OMEGA.cm, 10<-13>(A/ V.cm)>J/E, and I1/I2<=1. |
