PURPOSE:To obtain a superior electrophotographic sensitive body causing no defect in character printing at the time of reversal development and not rising in residual potential at the time of operation under low temperature environmental conditions by using for an undercoat a film obtained by hardening a composition containing an ionizable low molecular weight compound, a polyamide resin, and a thermosetting resin. CONSTITUTION:The electrophotographic sensitive body is formed by laminating the undercoat and a photosensitive layer containing an electric charge generating material and a charge transfer material on a conductive carrier made of a paper sheet or plastic film subjected to a conductivity enhancing treatment, and the undercoat is the film obtained by hardening a composition containing an ionizable low molecular weight compound such as tetracyanoethylene, a polyamide resin such as aliphatic polyamide resins, and a thermosetting resin such as a melamine resin, thus permitting the obtained electrophotographic sensitive body to be superior and to prevent defects in character printing at the time of reversal development (occurrence of black characters), and rising of residual potential at the time of operations under low temperature environmental conditions. |
