  • Patent number: 6368764
    Abstract: The present invention provides a photosensitive member for electrophotography which has excellent adhesion between a surface protective layer and a photosensitive layer as well as electrostatic properties, such as sensitivity and the like, and which prevents an occurrence of an image noise over a long period of time. The photosensitive member for electrophotography which comprises: (i) an electroconductive support, (ii) an organic photosensitive layer which comprises a charge generating material, a charge transporting material, and a binder resin, and (iii) a surface protective layer which comprises a thermosetting silicone resin, said surface protective layer being prepared by applying a coating solution comprising the thermosetting silicone resin and a solvent, which can dissolve the binder resin and has a boiling point of 60-130° C. and a solubility parameter of 8-11, onto the organic photosensitive layer and then curing the applied coating solution.
