Abstract
The invention presents an electrophotosensitive material comprising a conductive substrate, a photosensitive layer formed on the conductive substrate, and, if necessary, a surface protective layer formed on the photosensitive layer, wherein an oxadiazole derivative expressed in a general formula (I): ##STR1## where R.sup.1 denotes an alkyl group, is contained as an electron transfer substance on the photosensitive layer and/or surface protective layer. This photosensitive material enhances the electron transfer capability, and hence the sensitivity is improved. At the same time, the residual potential of the photosensitive material is lowered, and the stability and durability against repeated exposures are enhanced.
