Abstract
The present invention relates to a photosensitive member comprising: an electrically conductive substrate, an organic photosensitive layer formed on or over the electrically conductive substrate, the organic photosensitive layer comprising an antioxidant and/or a charge transporting material, and a surface protective layer formed on the organic photosensitive member, characterized by that the antioxidant and/or the charge transporting material is (are) contained in a more increased quantity with being closer to the interface between the surface protective layer and the organic photosensitive layer.
Claims12
A electrophotographic photosensitive member comprising:
- an electrically conductive substrate,
- a surface protective layer, and
- a photosensitive layer formed between the substrate and the protective layer and including an antioxidant in such a manner that quantity of the antioxidant increases with being closer to the interface between the protective layer and the photosensitive layer.
A electrophotographic photosensitive member comprising:
- an electrically conductive substrate,
- a surface protective layer,
- a charge generating layer formed on the electrically conductive substrate, and
- a charge transporting layer formed between the charge generating layer and the protective layer and including an antioxidant in such a manner that quantity of the antioxidant increases with being closer to the interface between the protective layer and the photosensitive layer.
A electrophotographic photosensitive member comprising:
- an electrically conductive substrate,
- a surface protective layer, and
- a photosensitive layer formed between the substrate and the protective layer, said photosensitive layer comprising a first region containing an antioxidant and a second region containing an antioxidant more than the first region, the second region being positioned between the first region and the protective layer.
