ABSTRACT:
In accordance with a first aspect of the present invention, a system is provided for fusing an unfixed toner image to a substrate comprising a rotatable hot fusing roll and a backup belt assembly. The belt assembly may comprise a backup belt and a housing structure including a nip forming pressure roll. The backup belt may be wrapped about the housing structure including the nip forming pressure roll. Preferably, the pressure roll applies a force to the belt so as to form the sole nip region between the rotatable fusing roll and the backup belt.
