Abstract
An electrophotographic photoreceptor includes a conductive substrate and a photosensitive layer disposed on the conductive substrate which serves as an outermost surface of the electrophotographic photoreceptor. The electrophotographic photoreceptor satisfies YC−YA≥0.1 MPa, YC−YB≥0.1 MPa, and YC≤4.5 MPa, where YA, YB, and YC (MPa) represent the Young's moduli of a surface of the photosensitive layer determined by nanoindentation at an indentation depth of 500 nm at end portions A and B extending from a position 10 mm to a position 70 mm from the respective edges of the photosensitive layer toward the center of the photosensitive layer in an axial direction of the electrophotographic photoreceptor and a central portion C extending from a position 20 mm in front of and to a position 20 mm behind the center of the photosensitive layer in the axial direction of the electrophotographic photoreceptor, respectively.
