PURPOSE:To enhance electrophotographic characteristics by using a combination of selenium or selenium alloy particles as an electric charge generating material and a specified compound as a charge transfer material. CONSTITUTION:A charge generating layer 3 formed on a conductive substrate 1 contains the charge generating material 2 comprising trigonal selenium in a binder resin and a charge transfer layer 5 formed on the layer 3 contains the charge transfer material 4 comprising at least one of the compounds represented by formula I and at least one of the compounds represented by formula II, and in these formulae, R1 is alkyl, H, or alkoxy, and each of R2-R6 is alkyl, H, alkoxy, halogen, alkoxycarbonyl, or substituted amino, thus permitting the obtained electrophotographic sensitive body containing a combination of said charge generating material and said charge transfer materials to be superior in photosensitivity potential stability during cyclic uses, and resistance to rise of residual potential. |
