摘要： A heating device includes a heating rotator, a pressure rotator, a planar heater, and a holder. The pressure rotator is configured to press against the fixing rotator to form a nip through which the recording medium is conveyed. The planar heater includes a plurality of heat generators arranged side by side and at least one separation region between the plurality of heat generators. The holder holds the planar heater and contacts the planar heater in a pressure direction in which the pressure rotator presses the heating rotator. The holder includes at least one clearance structure configured to cause a contact area between the planar heater and a portion of the holder corresponding to the at least one separation region to be smaller than a contact area between the planar heater and a portion of the holder not corresponding to the at least one separation region.

The flanges are disposed at axial edges of the metal member in contact with an inner circumferential surface of the metal member. The first heater is disposed opposite the inner circumferential surface of the metal member to heat an axial middle portion of the metal member. The second heater is disposed opposite the inner circumferential surface of the metal member to heat axial end portions of the metal member. The first heater is disposed farther from the nip than the second heater.

摘要： A fixing device includes a fixing rotary body, an opposed member, a heater, and a heating controller. The opposed member opposes the fixing rotary body to form a nipping portion therebetween. The heater includes heat generators arranged in a width direction of a recording medium. When the recording medium fed to the nipping portion has an image area and a non-image area, the heating controller controls the outputs of the heat generators based on image information so that a first heat generator of the heat generators corresponding to the image area is higher in temperature and a second heat generator of the heat generators corresponding to the non-image area is lower in temperature. Based on information other than the image information, the heating controller temporarily shifts an area of the fixing rotary body corresponding to the non-image area to a temperature differing from a normal temperature.
