Abstract
Provided is an electrophotographic belt having excellent creep resistance and digital reproducibility. The electrophotographic belt is composed of a biaxially stretched cylindrical film, and the film includes a matrix including a thermoplastic resin and an electroconductive domain including an ionic electroconductive agent, and when a surface resistivity of the film in a circumferential direction is defined as A, and a surface resistivity of the film in a direction orthogonal to the circumferential direction is defined as B, A≥B is satisfied, and a tensile modulus of elasticity of the film in the circumferential direction is 1.0 GPa or more and 3.0 GPa or less.
