    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.

    摘要： The present invention relates to an electrophotographic photosensitive member having a support and provided thereon a photosensitive layer. The photosensitive layer contains a high-molecular weight charge-transporting material having a specific repeating structural unit. The high-molecular weight charge-transporting material has a weight-average molecular weight Mw of 1,500 or more and an energy level of highest occupied molecular orbital, EHOMO, of from −8.3 eV or more to −8.0 eV or less as found by semiempirical molecular-orbital calculation. The present invention also relates to a process cartridge and an electrophotographic apparatus which have such an electrophotographic photosensitive member.

    摘要： An electrophotographic photosensitive member is constituted by a support and a photosensitive layer disposed on the support. The electrophotographic photosensitive member has a surface layer comprising a polyester resin having a recurring unit represented by the following formula (1): wherein A1 represents a substituted or unsubstituted divalent aliphatic hydrocarbon group. The resultant surface layer is effective in improving an abrasive resistance of the photosensitive member.
