Abstract
A fixing device applicable to image forming equipment and cable of controlling the amount of silicone oil to be applied to a heat roller. Silicone oil is applied to the heat roller via applicator felt, a second application roller and a first application roller. An upper and a lower scraper blade contact the surface of the second application roller to regulate the silicone oil on the second application roller to a predetermined small amount. While one of the scraper blades so regulates the amount of silicone oil on the second application roller, the other scrapes offset toner particles, paper dust and other impurities off the application roller.
