Abstract
Abstract An electrophotographic light-sensitive member comprising a conductive support, a photoconductive layer and a protective outer layer, the protective outer layer comprising at least one particulate metal oxide having a mean particle size below about 0.3 μm dispersed in an organic resin binder material. The electrophotographic light-sensitive member may be prepared by initially forming the protective outer layer and thereafter applying the photoconductive layer and conductive support thereto.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
67 words
A process for producing an electrophotographic light-sensitive member comprising providing a film comprising metal oxide particles having a mean particle size below about 0.3 micrometer dispersed in a resin, applying a layer of photoconductive material on said film, said film being substantially transparent in the wavelength region to which said layer of photoconductive material is sensitive, and applying a conductive layer to said layer of photoconductive material.
Claim 2
Dependent Claim
67 words
A process for producing an electrophotographic light-sensitive member comprising providing a film comprising metal oxide particles having a mean particle size below about 0.3 micrometer dispersed in a resin, applying a layer of photoconductive material on said film, said film being substantially transparent in the wavelength region to which said layer of photoconductive material is sensitive, and applying a conductive layer to said layer of photoconductive material.
Claim 3
Dependent Claim
97 words
A process for producing an electrophotographic light-sensitive member comprising providing a removable member having a surface with release properties, forming a protective layer on said surface, said protective layer comprising metal oxide particles having a mean particle size below about 0.3 micrometer dispersed in an organic resin binder material, applying a layer of photoconductive material on said protective layer, said protective layer being substantially transparent in the wavelength region to which said layer of photoconductive material is sensitive, applying a conductive layer to said layer of photoconductive material, and removing said removable member from said protective layer.
Claim 4
Dependent Claim
97 words
A process for producing an electrophotographic light-sensitive member comprising providing a removable member having a surface with release properties, forming a protective layer on said surface, said protective layer comprising metal oxide particles having a mean particle size below about 0.3 micrometer dispersed in an organic resin binder material, applying a layer of photoconductive material on said protective layer, said protective layer being substantially transparent in the wavelength region to which said layer of photoconductive material is sensitive, applying a conductive layer to said layer of photoconductive material, and removing said removable member from said protective layer.
Claim 5
Dependent Claim
27 words
A process for producing an electrophotographic light-sensitive member according to claim 1 wherein said film has a thickness of between about 2 micrometers and about 20 micrometers.
Claim 6
Dependent Claim
27 words
A process for producing an electrophotographic light-sensitive member according to claim 1 wherein said metal oxide particles have a mean particle size less than about 0.1 micrometer.
