A cleaning roller that rotates in contact with the heating roller on the downstream side in the rotational direction of the heating roller from a pressure contact position of the heating roller and the pressure roller, and a bearing member that pivotally supports a rotating shaft of the cleaning roller. , a cleaning roller unit comprising a cleaning roller mounting plate to which the bearing member is fixed is provided, and the cleaning roller mounting plate is hinged to the casing of the fixing device, so that the cleaning roller unit is attached to the casing of the fixing device. A fixing device characterized in that it is configured so that it can be rotated to open and close. (2) The open transfer material of the cleaning roller unit is held and conveyed by a heating roller equipped with an internal heat source such as a heater that rotates in pressure contact with the roller, and a pressure roller that is in pressure contact with the heating roller, and the heating roller is applied. The toner is melted by pressure and heat and thermally fixed onto the transfer material. In a general heating roller type fixing device, the heating roller is located on the upper side. The heating roller has heating means such as a heater inside the pipe-shaped metal roller. The pressure roller that comes into pressure contact with the heating roller is formed by wrapping, for example, silicone rubber around the circumferential surface of a core metal. The surface temperature of the heating roller is maintained at around 200° C. by heating means, and the heating roller is rotated in one direction by power. On the other hand, the pressure roller presses against the heating roller from behind the transfer material and rotates as a result of the fixation of the transfer material. Then, while the transfer material passes through a fixing device, the toner image is fused and fixed, and then the transfer material is discharged to the outside.
