ABSTRACT:
An electrophotographic photosensitive member is constituted by a support and a photosensitive layer disposed on the support. The photosensitive layer includes a fluorene compound represented by a formula (1) and a stilbene compound represented by a formula (4). The compounds of the formulas (1) and and (4) may preferably be used as a charge transport material. The combination of such compounds is effective in improving resistances to abrasion, crack and crystallization of the resultant photosensitive layer.
