Abstract
A photosensitive member for electrophotography having a photosensitive layer containing a hydrazone compound represented by the following general formula [I]: ##STR1## wherein R.sup.1 and R.sup.2 independently represent a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom; R.sup.3 represents a halogen atom; m is 1 or 2; and n is 0, 1 or 2. The photosensitive member has not only extremely high sensitivity but also sufficiently low residual potential. It is also highly resistant to fatigue so that the repeated use provides it with little accumulation of residual potential and little variation of surface potential and sensitivity.
