ABSTRACT:
A fuser having an oil applying felt composed of fluororesin fibers and touching to an oil applying roller. The oil applying felt is dipped in oil preserved in an oil tank at one end, so that the oil is elevated through capillarity and supplied to the oil applying roller. The oil applied over the oil applying roller is leveled by an oil limiting blade, and the oil thus leveled is applied to a fusing roller touching the oil applying roller. Meanwhile, a sheet having thereon formed a non-fused toner image is heated and pressed respectively by the fusing roller and a pressure applying roller, whereupon the non-fused toner on the sheet adheres to the fusing roller. The toner then adheres to the oil applying felt through the oil applying roller. However, the oil applying felt is not clogged with the toner because it is made of the fluororesin fibers.
