Abstract:
The present invention provides an electrophotographic photosensitive member in which a photoconductive layer is an amorphous layer that contains a silicon atom as a main component, and a surface layer contains an aluminum atom, a zinc atom and an oxygen atom so as to satisfy Expression (1) and Expression (2): 3.0≦100{y/(x+y)}≦7.0 (1), and 1.05≦z/(1.50x+y)≦1.20 (2), in Expression (1) and Expression (2), x represents atom % of the aluminum atom contained in the surface layer, y represents atom % of the zinc atom contained in the surface layer, and z represents atom % of the oxygen atom contained in the surface layer.
