Claims
- 1. A method of manufacturing an electrophotographic photosensitive member having a substrate provided thereon with at least a photoconductive layer, by a process comprising the steps of:
- (a) cutting the surface of said substrate;
- (b) cleaning the cut substrate with water;
- (c) in 30 minutes or less after said water- cleaning step, bringing the water-cleaned substrate into contact with an alcohol medium, said alcohol medium at a temperature from 10.degree. C. to 50.degree. C. and said alcohol medium contact step conducted over a period from 10 seconds to 10 minutes; and
- (d) forming said photoconductive layer on the substrate having been contacted with said alcohol medium.
- 2. The method according to claim 1, wherein said alcohol medium is selected from the group consisting of methyl alcohol, ethyl alcohol, propyl alcohol and isopropyl alcohol.
- 3. The method according to claim 1, wherein said alcohol is of second grade or higher.
- 4. The method according to claim 1, wherein in said step of cutting the substrate surface an oxide film present on the substrate surface is removed.
- 5. The method according to claim 1, wherein said alcohol medium contact step is carried out after the substrate is rinsed with pure water after said water cleaning step.
- 6. The method according to claim 1, wherein an ultrasonic wave is used in said water cleaning step.
- 7. The method according to claim 1, wherein said photoconductive layer comprises a non-monocrystalline material containing at least a silicon atom.
- 8. The method according to claim 1, wherein said process further comprises the step of forming a surface layer on said photoconductive layer.
- 9. The method according to claim 8, wherein said surface layer comprises a non-monocrystalline material containing at least a silicon atom.
- 10. The method according to claim 1, wherein at least one of an infrared absorbing layer and/or a charge injection blocking layer is formed on the substrate having been subjected to said water-contact step, followed by said step of forming said photoconductive layer.
- 11. The method according to claim 10, wherein at least one of said infrared absorbing layer and/or said charge injection blocking layer comprises a non-monocrystalline material containing a silicon atom.
- 12. The method according to claim 11, wherein said infrared absorbing layer further contains a germanium atom.
- 13. The method according to claim 11, wherein said charge injection blocking layer further contains a Group III atom or a Group V atom of the periodic table.
- 14. The method according to claim 9, wherein said surface layer further contains a carbon atom.
- 15. A method of treating a substrate for an electrophotographic photosensitive member by a process comprising the steps of:
- (a) cutting the surface of said substrate;
- (b) cleaning the cut substrate with water; and
- (c) in 30 minutes or less after said water-cleaning step, bringing the water-cleaned substrate into contact with an alcohol medium, said alcohol medium at a temperature from 10.degree. C. to 50.degree. C. and said alcohol medium contact step conducted over a period from 10 seconds to 10 minutes.
- 16. The method according to claim 15, wherein said alcohol medium is selected from the group consisting of methyl alcohol, ethyl alcohol, propyl alcohol and isopropyl alcohol.
- 17. The method according to claim 15, wherein said alcohol is of second grade or higher.
- 18. The method according to claim 15, wherein in said step of cutting the substrate surface an oxide film present on the substrate surface is removed.
- 19. The method according to claim 15, wherein said alcohol medium contact step is carried out after the substrate is rinsed with pure water after said water cleaning step.
- 20. The method according to claim 15, wherein an ultrasonic wave is used in said water cleaning step.
