ABSTRACT:
A thermal fusing device for softening toner images is provided in combination with a transport at the exit of the fuser which transport is characterized by a pair of nip-forming members one of which is provided with a plurality of recesses for receiving belt structures fabricated from a silicone rubber material. A second roll is provided also having recesses for receiving the belts and this roll is positioned remotely from the first mentioned roll so that the belts are entrained about the two rolls such that they protrude from the recesses to thereby provide a nip-forming roll wherein only the belts contact the toner material carried by the copy substrate. Additionally, a fan is provided for cooling the surface of the belt so that the toner will more readily solidify and the paper can be stripped therefrom due to the beam strength of the paper.
