Abstract:
1. A cylindrical conductive belt for electrophotography comprising: a continuous phase which comprises a thermoplastic polyester resin; and discontinuous phases each of which comprises any one or both selected from a polyether-ester amide and a polyether amide, wherein the discontinuous phases are present in such a way as to extend in the peripheral direction of the cylindrical conductive belt, wherein the extension of the discontinuous phase in the peripheral direction of the cylindrical conductive belt is greater than that in the perpendicular direction of the cylindrical conductive belt, wherein a crystallinity of an outer-peripheral surface side of the cylindrical conductive belt is lower than that of an inner-peripheral surface side of the cylindrical conductive belt, wherein the crystallinity of the outer-peripheral surface side of the cylindrical conductive belt ranges from 40 to 55%, and the crystallinity of the inner-peripheral surface side of the cylindrical conductive belt ranges from 45 to 61%, and wherein the thermoplastic polyester resin is polyethylene naphthalate or polyethylene terephthalate, and wherein the cylindrical conductive belt is an intermediate transfer belt.
