Abstract
A heating mechanism includes a paper transmitting path for carrying a paper, a fixing roller provided on this paper transmitting path, a pressurizing roller disposed so as to oppose the fixing roller, a heating roller provided apart from the fixing roller for applying heat indirectly to the fixing roller, a belt which is wound around the heating roller and the fixing roller in order to transmit a rotation driving force from the fixing roller to the heating roller and thermal energy from the heating roller to the fixing roller and makes a contact with the other side face of the paper passing between the fixing roller and the pressurizing roller, and a pair of first restricting members disposed with a gap from both end faces of the heating roller to guard both sides of the belt on the heating roller thereby restricting a shifting motion of the belt in the width direction.
