Abstract:
In the electrophotographic photosensitive member of the present invention, a plurality of convex portions having a longest diameter L1 in the generatrix direction of the electrophotographic photosensitive member of 30 μm or more arid a height H1 of 1 μm or more are formed on the surface of the electrophotographic photosensitive member, a plurality of convex portions corresponding to the convex portions formed on the surface of the surface layer are formed at the interface between the surface layer and a layer immediately below the surface layer, and the rate of fitting of the convex portions formed on the surface of the surface layer to the convex portions formed at the interface between the surface layer and the layer immediately below the surface layer is 20% or more and 200% or less.
