Belt transport device and belt fixing device

A belt transport device for an image forming apparatus to transport a transport object by gripping said transport object between an endless belt and a back-up member contacting said endless belt, said belt transport device comprising:

• a drive roller, a driven roller and said endless belt wound around said rollers, and said back-up member pressed against said drive roller through said endless belt, the surface layer of said drive roller being formed of an elastic material treated by a polishing process along the exterior surface thereof in a direction opposite the direction of powered rotation of said drive roller to allow transport of said belt.

An image forming device for forming images on a recording member comprising a belt fixing device for fusing an unfixed toner image on the recording member by transporting the recording member bearing an unfixed toner between a endless belt and a back-up member, said belt fixing device comprising:

• a fixing/drive roller, a driven roller heated by a heating means, and a heated endless belt wound around said fixing/drive roller and said driven roller, and wherein said endless belt is heated by said heating means, the surface layer of said fixing/drive roller being formed of an elastic material treated by a polishing process along the exterior surface thereof in a direction opposite the direction of powered rotation of said fixing/drive roller to allow transport of said belt.

An drive roller used in a belt transport device which transports a transport object with rotation of an endless belt driven by said drive roller, said drive roller comprising:

• a surface layer which is formed of an elastic material treated by a polishing process along the exterior surface thereof in a direction opposite the direction of rotation of the endless belt.
