Abstract
A fluoroelastomer composition free of metal or metal containing compounds, such as metal, metal alloys, metal salts or metal oxide suitable for the upper layer of a fuser roll which does not require the use of mercapto functional active release agents to prevent offset is provided. The fluoroelastomer compositions contain at least 23.4 mole percent hexafluoropropylene. They can be cured by electron beam treatment, fugitive base treatment or by the use of blocked/hindered bases.
Claims10
A fusing member for fixing toner particles to a recording medium, comprising a substrate and an outer layer of fluoroelastomer material on the substrate, the outer layer of fluoroelastomer material being a polymer including vinylidene fluoride and at least about 23.4 mole percent hexafluoropropylene and cured without the addition of metal containing material.
A fusing system for fusing toner to a recording medium, comprising a fuser roll having an outer surface formed of fluoroelastomer material including vinylidene fluoride and at least about 23.4 mole percent hexafluropropylene cured without metal containing material and a polysiloxane release agent fluid disposed on the surface of the fuser roll, the release agent substantially free of mercapto functional compounds.
