Fuser apparatus for adjusting gloss of a fused toner image and method for fusing a toner image to a receiver
Disclosed are apparatus and methods to adjust gloss of a fused toner image, and in particular to reduce differential gloss within the fused toner image so as to provide prints which more closely resemble lithographic prints in image quality. In embodiments, the apparatus and methods employ a finishing member having an outer contact surface thereon which contacts a previously fused toner image under conditions of elevated temperature and pressure. The contact surface is comprised of a fluorocarbon thermoplastic random copolymer co-cured with a fluorinated resin, such as polyfluoroethylenepropylene (FEP). In embodiments, the contact surface comprises a fluorocarbon thermoplastic random copolymer co-cured with a fluorinated resin including subunits of:&#8212;(CH2CF2)x&#8212;, &#8212;(CF2CF(CF3))y&#8212;, and &#8212;(CF2CF2)z&#8212;,wherein:x is from 1 to 50 or 60 to 80 mole percent,y is from 10 to 90 mole percent,z is from 10 to 90 mole percent, andx +y+z equals 100 mole percent.
