Abstract: A fixing belt heats and fixes a toner image. A pressure roller rotates the fixing belt while in contact with the fixing belt. A heater heats the fixing belt. A lubricating oil forms an oil film between the heater and an inner peripheral surface of the fixing belt. A pressure roller driver rotates the pressure roller so that the lubricating oil causes the fixing belt to be out of contact with the heater.

Abstract: A fixing device includes a fixing belt, a pressuring member, a heat source, a pressing member and a first heating stop device. The fixing belt is provided to be rotatable around a rotation axis. The pressuring member is configured to be rotatable and to come into pressure contact with the fixing belt so as to form a fixing nip. The heat source is arranged at an inner diameter side of the fixing belt, provided at a position displaced from the rotation axis and configured to heat the fixing belt. The pressing member is configured to press the fixing belt to a side of the pressuring member. The first heating stop device is configured to face an outer circumferential face of a closest part to the heat source of the fixing belt and to operate at a first operating temperature so as to stop the heat source from heating the fixing belt.

Abstract: A fixing device includes a cylindrical rotatable fixing belt, a flat heater, a safety device, a heater holding part and a pressuring member. The flat heater has a plurality of heat generating parts. The safety device is arranged across two adjacent heat generating parts to interrupt power supply to the heat generating parts in a case where temperature reaches a threshold value. The heater holding part holds the flat heater so that the flat heater comes into contact with an inner circumference face of the fixing belt. The pressuring member sandwiches the fixing belt with the flat heater to form a pressuring area for sandwiching and conveying a sheet between the fixing belt and the pressuring roller.

Abstract: A fixing device includes a heating body, a pressuring body, a temperature detecting part, a first frame supporting the heating body, a second frame supporting the pressuring body and a movement mechanism. The temperature detecting part has a detecting element detecting an infrared ray radiated from the heating body and detects temperature of the heating body by the detecting element. The first frame includes a heat interrupting member covering the heating body between the heating body and the temperature detecting part. The movement mechanism moves the first frame in an approaching direction or a separating direction from the second frame to establish the heating body and the pressuring body in a pressurization state or a depressurization state. The heat interrupting member includes an aperture elongated in a movement direction of the first frame to pass the infrared ray radiated from the heating body to the detecting element through the aperture.
