Abstract: Plural main cores and plural sub-cores are arranged spaced apart from each other along a direction orthogonal to a rotating direction of a heat belt. The plural main cores are opposed to a first area where a sheet having first width in the heat belt passes. The plural sub-cores are opposed to second areas that are areas excluding the first area in an area where the sheet having second width larger than the first width in the heat belt passes. The plural sub-cores have thickness in the direction orthogonal to the rotating direction of the heat belt smaller than the thickness of the plural main cores.
