Abstract:
An electrophotographic photosensitive member includes a substrate, a photoconductive layer, an intermediate layer, and a surface layer sequentially formed. The intermediate layer contains silicon, carbon and hydrogen, and a distribution of a hydrogen ratio, which is a ratio of the number of hydrogen atoms to the number of silicon, carbon and hydrogen atoms, in the intermediate layer has a maximum region. A largest hydrogen atomic ratio in the intermediate layer is larger than a hydrogen atomic ratio in the surface layer, and the hydrogen atomic ratio in the surface layer is 0.30 to 0.45. A distribution of a carbon atomic ratio, which is a ratio of the number of carbon atoms to the number of silicon and carbon atoms, in the intermediate layer has a maximum and a minimum region. A carbon atomic ratio in the maximum region is 0.53 to 0.63, a carbon atomic ratio in the minimum region is 0.47 or more, and the maximum hydrogen region in the intermediate layer is partially superimposed on the minimum carbon region.
