Claim 0:
1. An electrophotographic belt having an endless shape and comprising a substrate,
the substrate containing a polyimide resin and carbon nanotubes,
a content of the carbon nanotubes in the substrate being 15 vol % or less with respect to a total volume of the polyimide resin,
the substrate having a tensile strength of 200 MPa or more in each of a peripheral direction thereof and a direction perpendicular to the peripheral direction, and
the substrate having a thermal conductivity of 0.9 W/(m·K) or more in a thickness direction thereof,
wherein when measuring a surface of the substrate by a reflection X-ray diffraction method, and an intensity of a diffraction peak derived from a (100) crystal plane of each of the carbon nanotubes is represented by I(100) and an intensity of a diffraction peak derived from a (002) crystal plane of each of the carbon nanotubes is represented by I(002), a ratio I(002)/I(100) is 35 or less.
