Abstract
An apparatus for fusing toner images to a receiver or copy sheet of paper includes a pressure roller and an axially unsupported fuser roller that is nested rotatably between the pressure roller and a pair of heater rollers. The apparatus of the present invention is particularly suitable for fusing toner images to the receiver or copy sheet without generating fuser related defects such as copy distortions, copy curls, wrinkles or image voids.
