Abstract
PURPOSE:To make it difficult to make toner adhere to the surface of a roller and to improve the quality of an image at the time of fixing by coating the peripheral surfaces of a heating roller and a pressurizing roller with a tetrafluoroethylene-perfluoroalkylvinylether copolymer (PFA) tube by specifying its thickness. CONSTITUTION:The PFA tube whose thickness is 20-100mum is applied to the outside of the core bar of the heating roller 1. And the PFA tube having the same thickness is applied to the outside of the silicone gum layer of the pressurizing roller 2. Said PFA tube has a small abrasion factor and provides the quality of repeling watery substance and oily substance, and also it is excellent in dielectric characteristic. Therefore, the peripheral surface of the roller 1 can be always kept clean and the quality of the image at the time of fixing can be improved by installing a cleaning roller 11, a destaticizing brush 12 and an oil impregnating roller 13.
