Provided are the following: a fixing device with which reduced is the torque required by a drive unit during a temperature elevating period in which the temperature of a rotating body is elevated; and an image forming device provided with the fixing device. A fixing device (5) is provided with the following: a fixing belt (520); a pressurizing roller (51); a first motor (M1); a halogen heater (522); a pressurizing mechanism (7); and a control unit (60). If the temperature of the fixing belt (520) is lower than a prescribed threshold value, the control unit (60) controls the pressurizing mechanism (7), and in a state where the pressing force acting on the pressurizing roller (51) of the fixing belt (520) is set to a first pressing force, the control unit causes the fixing belt (520) and the pressurizing roller (51) to rotate and heats the fixing belt (520) using a halogen heater (522). When the temperature of the fixing belt (520) becomes greater than the threshold value as a result of the heating, the pressurizing mechanism (7) is controlled and the pressing force is set to a second pressing force greater than the first pressing force. |
