ABSTRACT:
A laminated seamless belt having at least a base layer and an outer layer. The base layer contains a polyester thermoplastic elastomer as its main component. The base layer has a volume resistivity set to not less than 1.0×106(Ω·cm) nor more than 1.0×1011(Ω·cm). A volume resistivity of the outer layer is set to not less than 1.0×1011(Ω·cm) and not less than 10 times as large as that of the base layer. The base layer and the outer layer are formed by laminated extrusion.
