The invention relates to an electrophotographic photoreceptor which can suppress occurrence of abnormalities such as peeling or falling off of a film from a substrate end portion in a film formation step of a surface layer and maintain and reproduce a stable printing quality even in a use stage after productization, and an image forming apparatus including the same. An electrophotographic photoreceptor (1A) includes a cylindrical substrate (20) including a chamfered face (20b) located between an substrate outer circumferential surface (20a) and a substrate end face (20c), and a surface layer (13) located on the outer circumferential surface. The substrate outer circumferential surface (20a) includes a first uneven portion (U). The chamfered face (20b) includes a second uneven portion (V) and a third uneven portion (W) located on a surface of the second uneven portion (V).
