Abstract
A fixing device includes an elastic fixing roller, an endless belt, a pressing roller and a stretching part. The endless fixing belt is wound around the fixing roller with play. The pressing roller presses the fixing roller via the fixing belt to deform the fixing roller and forms a pressing area between the pressing roller and the fixing belt. A sheet passes through the pressing area. The stretching part is configured to pull the fixing belt in a direction opposite to the pressing roller and to stretch the fixing belt when a conveyance speed of the sheet conveyed to the pressing area is slower than a reference conveyance speed. The stretching part is configured to restrain deformation of the fixing roller to the pressing roller and to shorten length of the pressing area along a conveyance direction of the sheet.
