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 electrophotographic 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.
摘要:
An electrophotographic photosensitive member has a light-transmissive electroconductive substrate and a photosensitive layer on said substrate, the photosensitive layer includes a charge generating material and a charge transporting material, the number of the photoconductive carriers formed by the charge generating material and the substrate being more than the number of the photoconductive carriers formed by the charge generating material and the charge transporting material.
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 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.
