Abstract

In an electrophotographic light-sensitive material having on a conductive support a light-sensitive layer composed of a charge generating material and a charge transporting material. A hydrazone compound is used as the charge transporting material for providing the light sensitive layer having high sensitivity and less residual surface potential. The light-sensitive layer is stable to oxidation by ozone generated by corona discharging as well as to heat and light, results in less dark decay of the surface potential. Furthermore, the layer shows less deviation in residual potential and sensitivity due to repeated use.
