Abstract

PURPOSE:To obtain a sensitive receptor having flat sensitivity over the whole visible range and the wavelength range of a semiconductor laser and superior endurance by adding a specified trisazo compound to a charge generating layer and a specified hydrazone compound to a charge transferring layer. CONSTITUTION:A charge generating layer contg. a triphenylamine type trisazo compound represented by formulaIis formed on an electrically conductive support. A charge transferring layer contg. a hydrazone compound represented by formula II[where each of R1-R4 is H, 1-3 C alkyl, 1-3 C alkoxyl, (substituted) dialkylamino, dibenzylamino or halogen]is then formed on the charge generating layer. Thus, an electrophotographic receptor having high sensitivity over the whole visible range and the wavelength range of a semiconductor laser and superior endurance is obtd.
