Abstract: A fixing device includes a fixing belt, a pressuring roller pressured to the fixing belt, a heat source heating the fixing belt, a pressing member pressing the fixing belt toward the pressuring roller's side, and a sliding contact sheet interposed between the fixing belt and the pressing member to hold lubricant. The sliding contact sheet includes a sliding contact portion arranged at the center in a sheet conveying direction to come into contact with the fixing belt, a first fixed portion arranged at an upstream side in the conveying direction and wound around the pressing member at the heat source's side, and a second fixed portion arranged at a downstream side in the conveying direction and wound around the pressing member at the heat source's side from the first fixed portion. The sliding contact sheet is configured so that the second fixed portion becomes smaller than the first fixed portion.

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 moving 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 moving 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.

Abstract: A fixing device includes a fixing belt, a pressuring member, a heat source, a pressing member, a temperature sensor and a controller. A detected region whose temperature is detected by the temperature sensor is formed in the fixing belt, and an elastic layer of the detected region is provided with a hole in a part thereof in a circumferential direction. The controller judges that the fixing belt is rotating in a case where the temperature detected by the temperature sensor alternately increases and decreases in a state that the heat source is heating the fixing belt, and judges that the fixing belt is not rotating in a case where the temperature detected by the temperature sensor does not alternately increase and decrease in the state that the heat source is heating the fixing belt.

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 fixing belt, a pressuring member, a heat source, a moving member and a biasing member. The moving member is movable between a first position where the moving member blocks the radiant heat from the heat source to the fixing belt and a second position where the moving member does not block the radiant heat from the heat source to the fixing belt. The biasing member biases the moving member to the first position. The moving member moves from the first position to the second position by a friction force between the fixing belt and the moving member against a biasing force of the biasing member when the fixing belt is rotated. The moving member moves from the second position to the first position by the biasing force of the biasing member when a rotation of the fixing belt is stopped.
