摘要： An electrophotographic photosensitive member is constituted by disposing a photosensitive layer on an electroconductive support. The photosensitive layer is characterized by containing a specific fluorene compound or by containing another specific fluorene compound and a specific triphenylamine compound. The photosensitive layer is suitable for providing an electrophotographic apparatus showing excellent electrophotographic characteristics such as a high photosensitivity, a good potential stability in repetitive use, a decreased transfer memory, no crack in the photosensitive layer and no crystallization of a charge-transporting material.
