Abstract
The present invention provides an electrophotosensitive material comprising a conductive substrate and a single photosensitive layer containing a stilbene derivative (hole transferring material) represented by the general formula (1): ##STR1## (wherein R.sup.1, R.sup.2, R.sup.5 and R.sup.6 are the same or different and represent an alkyl group, an alkoxy group, an aryl group, an aralkyl group or a halogen atom; m, n, p and q are the same or different and represent an integer of 0 to 3, with the proviso that m and n represent a different integer when substituents represented by R.sup.1 and R.sup.2 are the same and that p and q represent a different integer when substituents represented by R.sup.5 and R.sup.6 are the same; and R.sup.3 and R.sup.4 are the same or different and represent a hydrogen atom or an alkyl group) and an electron transferring material, which is provided on the conductive substrate. This photosensitive material has high sensitivity and can be applied to any of positive and negative charging types with a single construction, and is also superior in optical characteristics.
