Disclosed is a conductive endless belt which is suppressed in gloss deterioration during use which is caused by friction with paper or a cleaning blade. Specifically disclosed is a conductive endless belt which is used in an image forming device. The conductive endless belt is characterized in that the base resin is composed of a polyalkylene terephthalate resin, a thermoplastic resin containing a naphthalene ring and/or a thermoplastic elastomer containing a naphthalene ring and which has a melting point higher than that of the polyalkylene terephthalate resin. The conductive endless belt is also characterized in that the mass ratio between the polyalkylene terephthalate resin and the thermoplastic resin containing a naphthalene ring and/or the thermoplastic elastomer containing a naphthalene ring in the base resin is within the range from 90/10 to 50/50.
