ABSTRACT:
A copy machine toner fixing device is provided having a plurality of rollers in which adjacent rollers are in contact under pressure, wherein at least one of the rollers is covered with a non-adhesive coating layer and copy paper carrying toner images thereon is passed between the rollers to fix the toner images on the paper, characterized in that the coating layer is an open celled, cellular plastic film wound around the periphery of the roller. A preferred film is expanded, porous polytetrafluoroethylene. The outer surface of the coating layer may advantageously be rendered non-porous by application of compression forces externally to the coating layer. Electroconductive filler may be advantageously incorporated into the open celled plastic film.
