PURPOSE:To obtain a high-sensitivity electrophotographic sensitive body by incorporating a specific imidazolidinilidene deriv. into an electric charge transfer material. CONSTITUTION:The charge transfer material of the electrophotographic sensitive body provided with a layer contg. the charge transfer material and charge generating material on a conductive base contains the imidazolidinilidene deriv. expressed by the formula I. In the formula I, R1-R4 denote a hydrogen atom, halogen atom, etc.; A1-A4 denote a hydrogen atom, alkyl group, etc. Since this imidazolidinilidene deriv. has substantially no absorption to light of >=500nm wavelength, the charge generating material, i.e., the material which generates an electric charge by reacting sensitively with light is used together. The electrophotographic sensitive body having excellent electrophotographic characteristics is thereby obtd. |
