摘要：
A fixing device, which fixes an unfixed toner image on a recording medium, includes a heating roller, a fixing roller, a pressurizing roller, and an endless belt that stretches over the heating roller and the fixing roller. A heat source and a heat pipe are arranged in a heating roller. The heat pipe substantially uniformly heats the surface of the heating roller.
