摘要： A fixing device includes a fixing rotary body and a heater disposed opposite the fixing rotary body. A heat shield is movable in a circumferential direction of the fixing rotary body and interposed between the heater and the fixing rotary body to shield the fixing rotary body from the heater. An overheating suppressor is interposed between the heater and the heat shield to shield the heat shield from the heater. The heat shield includes an intermediate portion spanning in the circumferential direction of the fixing rotary body and movable between a shield position where the intermediate portion is disposed opposite the heater directly and a retracted position where the intermediate portion is disposed opposite the heater via the overheating suppressor.

摘要： A fixing device includes a rotary fixing member, a heater, a pressing member, a nip formation member, a reinforcement member, a sliding sheet, and a holding member. The nip formation member is disposed at an inner circumferential side of the fixing member and pressed by the pressing member via the fixing member to form a nipping portion. The reinforcement member is stationarily disposed in an internal diameter area of the fixing member to support the nip formation member. The sliding sheet is disposed between the nip formation member and an inner circumferential face of the fixing member. The holding member is disposed at a member differing from the nip formation member to hold the sliding sheet in a state in which the sliding sheet is in close contact with a nipping face of the nip formation member facing the nipping portion.

摘要： A fixing device includes a fixing rotary body rotatable in a predetermined direction of rotation and a heater disposed opposite and heating a heating span of the fixing rotary body. A controller is operatively connected to a power supply that supplies power to the heater and a driver that rotates the fixing rotary body to control the power supply and the driver. The controller performs at least one of a rotation speed control that controls the driver to rotate the fixing rotary body at an increased rotation speed and a power supply control that controls the power supply to supply an increased amount of power to the heater.
