PROBLEM TO BE SOLVED: To provide a conductive endless belt capable of exhibiting excellent toner releasability not only in an environment at normal temperature and normal humidity but also in an environment at high temperature and high humidity in addition to various required performances of a belt such as elastic modulus, strength and charging characteristics, and capable of satisfying required performances also in respect of glossiness and setting resistance, and an image forming apparatus using the same. SOLUTION: The conductive endless belt 10 for tandem system transfer and transport is circularly driven by a driving member 9 to transport a recording medium held by electrostatic attraction to four image forming units 1, where respective toner images are sequentially transferred onto the recording medium. The conductive endless belt is produced by extrusion molding and comprises a polypropylene-based resin, a crystal nucleus agent, and a carbon black and/or a high molecular ionic conduction agent.
