A heating roller fixing method and apparatus in which recording paper (14) bearing a toner image (13) thereon is conveyed by a heating roller (1) and a pressure roller (5) in pressure contact with said heating roller (1) to heat-fix said toner image, and a cleaning member (8) having a fiber material containing a high viscosity mold releasing agent on the surface thereof is brought into pressure contact with said heating roller (1). In an alternative embodiment, the clearing member may be a web urged against the fixing roller by a roller. The high viscosity agent may have a viscosity of 1,500-300,000 centistokes at 25 DEG C (preferably 2,000-60,000 cs), and be a silicone oil. The method and apparatus are of particular use in fixing a toner which includes a styrene homopolymer or copolymer with molecular weight at least 100,000 and a polyester containing at least 5% by wt. of a chloroform-insoluble component. <IMAGE> |
