Abstract
The present disclosure relates to a fusing system for fusing toner to a recording medium. In one embodiment, the fusing system contains a fuser roller configured as a heat pipe including an inner tube and a coaxial outer tube that is mounted to the inner tube, the inner and outer tubes defining an interior space therebetween that is adapted to contain a liquid and to be evacuated so as be maintained in a vacuum, and a pressure roller in contact with the fuser roller. In another embodiment, the fusing system contains a fuser roller, a pressure roller in contact with the fuser roller, and an external heating roller in contact with the fuser roller, the external heating roller being configured as a heat pipe including an inner tube and a coaxial outer tube that is mounted to the inner tube, the inner and outer tubes defining an interior space therebetween that is adapted to contain a liquid and to be evacuated so as be maintained in a vacuum.
