The present invention provides an electrophotographic photosensitive member which has a substrate, a photoconductive layer and a surface layer formed from hydrogenated amorphous silicon carbide in this order. The average value of the carbon content (C/(C+Si)) of the surface layer formed from the hydrogenated amorphous silicon carbide is set at 0.90 or more and less than 1.00, and the average value of the hydrogen content (H/(H+C+Si)) is set at 0.40 or less; and when the average value of the ratios of the sum of a SiO bond and an OSiO bond in the outermost surface region that constitutes a range within a depth of 5 nm or less from the outermost surface of the surface layer is represented by a, and an average value of the silicon content (Si/(C+Si)) is represented by b, 0.015a*b0.090 holds.

An electrophotographic photoreceptor includes: a cylindrical base body having a two-step stepped chamfer between a base body outer peripheral face and a base body end face; and a surface layer located on the base body outer peripheral face. The cylindrical base body has an outer chamfered face and an inner chamfered face lying closer to an end face than the outer chamfered face. A length L2 of the inner chamfered face is larger than a length L1 of the outer chamfered face, namely L1<L2, as viewed in lateral section taken along a rotation axis of the cylindrical base body.
