ABSTRACT:
A fuser member for applying heat and pressure to fuse toner to a recording medium which does not require use of mercapto functional release agents has a surface of a fluoroelastomer material including vinylidene fluoride and at least about 23.4 mole percent hexafluoropropylene. High hexafluoropropylene molar content at least as high as about 30.0 mole percent and preferably 38.1 mole percent may be utilized. When the fluoroelastomer material is a copolymer of vinylidene fluoride and hexafluoropropylene, the fluorine content is between about 69-71%. Such fuser members may be utilized alone or with polysiloxane release agents which do not include mercapto functional compounds.
