The present invention relates to a benzidine derivative represented by the general formula (1): ##STR1## wherein R.sup.1 to R.sup.6, m and n are as defined in the present specification. The benzidine derivative improves durability and heat resistance of a membrane containing the same while maintaining high hole transferring capability. Therefore, an electrophotosensitive material, which comprises a photosensitive layer containing the benzidine derivative, has high sensitivity and is superior in durability and heat resistance.
本发明涉及一种由通式(1)表示的苯胺衍生物:其中R.sup.1至R.sup.6,m和n如本说明书中所定义。该苯胺衍生物提高了含有该物质的膜的耐久性和耐热性,同时保持高孔传输能力。因此,包括含有该苯胺衍生物的感光层的电子感光材料具有高灵敏度,并且在耐久性和耐热性方面具有优越性。
