Abstract
The present invention provides a photosensitive member for electrophotography which has an excellent adhesion between a surface protective layer and a photosensitive layer and an excellent image quality at the time of plate wearing. In the photosensitive member for electrophotography wherein at least the photosensitive layer and the surface protective layer are laminated on an electroconductive support in this order, the characteristic is that said surface protective layer comprises at least fluorine-containing polysiloxane, ultraviolet absorber and electroconductive fine particles.
Claims18
A photosensitive member for electrophotography comprising:
- an electroconductive support,
- a photosensitive layer, and
- a surface protective layer comprising a binder resin consisting of a fluorine-containing polysiloxane, an ultraviolet absorber and electroconductive fine particles.
A method of producing a photosensitive member for electrophotography, which comprises
- forming a photosensitive layer on an electroconductive support, and
- forming a surface protective layer on said photosensitive layer by applying a coating solution comprising a reaction product of an organosilane with fluorine-containing silane coupling agent, an ultraviolet absorber and electroconductive fine particles, and curing said reaction product in the applied solution,
- said protective layer comprising fluorine-containing polysiloxane, the ultraviolet absorber and the electroconductive fine particles.
A photosensitive member for electrophotography comprising:
- an electroconductive support,
- a photosensitive layer, and
- a surface protective layer comprising a fluorine-containing polysiloxane, an ultraviolet absorber and electroconductive fine particles which are those subjected to a surface treatment with a treating agent represented by the following general formula (III):
- wherein each of R5, R6, R7, R8, R9 and R10 is independently a methyl group or an ethyl group, and n is an integer of 1 or more.
