Abstract
Concerned with a cylindrical conductive belt for electrophotography which has made permanent curl less occur. The conductive belt has a continuous phase containing a thermoplastic polyester resin and discontinuous phases each containing any one or both selected from a polyether-ester amide and a polyether amide, and the discontinuous phases are present in such way as to extend in the peripheral direction of the belt; the belt having a crystallinity that is lower on the outer-peripheral surface side than on the inner-peripheral surface side.
