Abstract

An oil transfer component for coating a fuser roll (2) in the fuser system of a plain paper copier (or laser printer) employs a porous polytetrafluoroethylene (PTFE) material formed from particles of granular-type polytetrafluoroethylene fused together such as to form a porous integral network of interconnected particles. It is usually in the form of a thin sheet of thickness 50-750 microns, optionally laminated to a backing material. It may be in roll form (6), either dry or pre-loaded with release oil, as a cover wick (20) for an oil reservoir (26), or laminated to a roller (30) or a reservoir material (40). The surface is textured to improve coating and wiping.
