PURPOSE:To improve sensitivity and potential stability of an electrophotographic sensitive body by using a specified tetraaza porphyrin deriv. and a tetraaza porphyrin metal complex salt deriv. CONSTITUTION:The title electrophotographic sensitive body contains at least one kind selected from a group consisting of tetraaza porphyrin derivs. expressed by the formula I and tetraaza porphyrin metal complex salt derivs. expressed by the formula II. In the formulas I and II, X is an H atom, heavy hydrogen atom, or an alkali metal atom; A is a residue expressed by the formula III, which may have a substituent; M is an Si atom or a metal atom other than alkali metal atoms; Y is a halogen atom, OH group, alkoxy group, or an O atom; n is an integer zero, 1, or 2. By this constitution, an electrophotographic sensitive body having high sensitivity and low residual potential is obtd. In this case, an example for synthesized pigment as expressed by the formula IV may be used. |
