摘要： A heating device includes a rotator, a heater, a heater holder, and a first high thermal conduction member. The heater includes a base and a plurality of heat generators being arranged on the base and including neighboring heat generators. The heater has a gap area between the neighboring heat generators. The first high thermal conduction member has a higher thermal conductivity than the base and faces the gap area.

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.

摘要： Disclosed is a weld joint of an aluminum alloy member formed by joining one end of a wrought material (12) to one end of a cast member (11). The cast member has a chamfer (14), and an inserting portion (13) which extends from the lower end of the chamfer (14) toward the distal end of the case member along the lower surface of the wrought material. The distance (L) from the lower end of the chamfer to the end face (12a) at one end of the wrought material is set equal to 1.0-1.7 times of the thickness (T) of the wrought material, and the chamfer is inclined so that the angle of a groove between the chamfer and the end face (12a) at one end of the wrought material is 15-45°.

摘要： A heating device includes a planar heater, a rotator, a pressure rotator, a heating device frame, a resistor, and a discharger. The pressure rotator has a conductive outer surface and presses the rotator. The heating device frame holds the pressure rotator. The discharger is in contact with the conductive outer surface of the pressure rotator and grounded via the resistor and the heating device frame.
