Abstract
An electrophotographic photosensitive element having a conductive support provided thereon with a photosensitive layer comprising a carrier-generating phase and a carrier-transporting phase. The carrier-transporting phase comprises a hydrazone compound to improve carrier-transporting ability having the formula ##STR1## wherein, X and Y each represent a hydrogen or a halogen, R.sub.1 and R.sub.2 each represent an aryl group which may have a substituent or substituents, and Ar represents an arylene group which may have a substituent or substituents.
