PURPOSE:To obtain an electrophotographic receptor having high sensitivity over the whole visible range and the wavelength rage of a semiconductor laser as well as superior endurance by forming a charge generating layer contg. a specified trisazo compound and a charge transferring layer contg. a specified hydrazone compound on an electrically conductive support. CONSTITUTION:A charge generating layer contg. a triphenylamine trisazo compound represented by formulaIis formed on an electrically conductive support, and on the charge generating layer a charge transferring layer contg. a hydrazone compound represented by formula II (where R1 is CH3, C2H5, CH2CH2OH or CH2CH2Cl, R2 is CH3, C2H5, benzyl or phenyl, and R3 is H, Cl, Br, 1-4C alkyl, alkoxy, dialkylamino or NO2) is formed to manufacture a receptor. Thus, the receptor with superior charging and photosensitive characteristics, etc. as well as superior endurance is obtd. easily. |
