ABSTRACT:
Disclosed are fuser members, apparatus and methods which employ compositions that can be varied to provide a fused toner image with a selected gloss level. In embodiments, the apparatus and methods employ a fusing member having an outer contact surface thereon which contacts a previously fused toner image under conditions of elevated temperature and pressure. The contact surface has a Gardner G60 gloss of up to about 35 and 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:in-line-formulae description="In-line Formulae" end="lead"?—(CH2 CF2)x-, —(CF2CF(CF3))y-, and —(CF2 CF2)z-,in-line-formulae description="In-line Formulae" end="tail"?wherein:x is from 1 to 50 or 60 to 80 mole percent,y is from 10 to 89 mole percent,z is from 10 to 89 mole percent, andx+y+z equals 100 mole percent.
