| 摘要 |
A negative-charging electrophotographic photosensitive member comprising an aluminum-based substrate and a silicate film and a light-receiving layer in this order. The silicate film has a layer thickness of 0.5 nm to 15 nm and comprises at least aluminum atoms, silicon atoms and oxygen atoms. The light-receiving layer has at least a lower-part charge injection blocking layer formed of a non-single crystal silicon film comprising at least silicon atoms, nitrogen atoms and oxygen atoms, not doped with any impurities, a photoconductive layer formed of a non-single crystal silicon film comprising at least silicon atoms, an upper-part charge injection blocking layer formed of a non-single crystal silicon film comprising at least silicon atoms, carbon atoms and atoms belonging to the Group 13 of the periodic table, and a surface protective layer formed of a non-single crystal silicon film comprising at least silicon atoms and containing carbon atoms.
