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"?>-(CH<SUB>2</SUB>CF<SUB>2</SUB>)x-, -(CF<SUB>2</SUB>CF(CF<SUB>3</SUB>))y-, and -(CF<SUB>2</SUB>CF<SUB>2</SUB>)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, and x+y+z equals 100 mole percent.
