    摘要： A fixing roller of an image fixing apparatus has an elastic layer on a core metal and has a thermal conductive fluororubber latex layer containing a mixture of fluororubber, fluororesin and thermal conductive fillers more outer side than the elastic. An intermediate layer made of silicone rubber having higher thermal conductivity than the thermal conductive fluororubber latex layer is provided between the thermal conductive fluororubber latex layer and the elastic layer, and the intermediate layer is configured so that an elastic parameter Y(=H×T) satisfies a relational expression: Y≧4200 where H (degree) is Asker-C hardness of the silicone rubber having higher thermal conductivity (500 g load) and T (μm) is a thickness of the silicone rubber having higher thermal conductivity.
