ABSTRACT:
In an image forming apparatus, a fixing device for fixing a toner image on a paper has an oil applying member for applying oil to a heat roller, and an impurity fixing member for fixing the impurities, including toner and paper dust, to the cleaning member. The impurities transferred from the applying member to the cleaning member are fixed to the cleaning member. As a result, the applying member suffers from a minimum of contamination and can be cleaned when contaminated. This obviates the reverse transfer of the contamination from the applying roller to the heat roller which would lower image quality.
