  • Heat fixing belt, method for producing heat fixing belt, and image fixing device
    Patent number: 10423105
    Abstract: This heat fixing belt is provided with a tubular belt base that is formed from an insulating heat-resistant resin, an elastic resistive heat generation layer that is formed from an elastic base material containing an elastic material and contains conductive material, a toner release layer, and a pair of electrode layers for feeding a power to the elastic resistive heat generation layer. The elastic resistive heat generation layer is provided on the outer circumferential surface of the belt base. The toner release layer is provided as the outermost layer. The pair of electrode layers are provided on both end portions of the outer circumferential surface of the elastic resistive heat generation layer, and have a volume resistivity that is lower than the volume resistivity of the elastic resistive heat generation layer.
    Type: Grant
