る定着装置のオフセツト防止機構。[Claims for Utility Model Registration] The recording paper on which the toner image has been transferred is passed between a pair of rollers to fix the toner image, and when the toner image is fixed, the toner is deposited on the surface of the pair of rollers. In the offset prevention mechanism of the fixing device that prevents transfer, a coating layer is formed on at least the surface of the roller on the side that comes into contact with the toner image of the pair of rollers to perform frictional charging. An offset prevention mechanism for a fixing device, wherein the coating layer is made of a material having frictional charge polarity that electrically repels toner against the surface of the roller.
