Abstract
A belt fusing apparatus for providing image gloss to a colorant image formed on a receiver member by a reproduction apparatus, the belt fusing apparatus, configured to substantially prevent line art type marking particle offset. The belt fusing apparatus is disclosed as including a heated fuser roller, with a pressure roller in nip relation with the fuser roller, and a steering roller. A fusing belt is entrained about the fuser roller and the steering roller. The steering roller is located downstream of the nip between the fuser roller and the pressure roller, relative to the fuser roller to provide a wrap for the fusing belt about a portion of between 10 and 30% of the circumference of the pressure roller. Further, a cooler is provided to cool the fusing belt over such wrap.
