    Abstract: An image transfer medium carrier member, for carrying an image transfer medium such as a recording paper sheet, has a substrate and a surface layer. The surface layer containing a polyester resin and a cured resin. An image forming apparatus comprises: an electrophotographic photosensitive member; a charging device for electrostatically charging the electrophotogrpahic photosensitive member; an image exposure device for exposing the electrophotographic photosensitive member to an image light so as to form an electrostatic latent image in the electrophotographic photosensitive member; a developing device for developing the electrostatic latent image with a toner so as to produce a toner image; and the above-mentioned image transfer medium carrier member.

    Abstract: An electrophotographic photosensitive member is constituted by disposing a photosensitive layer on an electroconductive support. The photosensitive layer is characterized by containing a specific polycarbonate having a side chain comprising a charge-transporting group formed by nitrogen atom and benzene ring. The charge-transporting group may preferably has a specific triphenylamine structure, hydrazone structure or biphenyldiamine structure. 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.
