Abstract
In an image heating device including a heater including a substrate, a first conductor provided on the substrate, a second conductor provided at a position different from the first conductor on the substrate in a direction orthogonal to a longitudinal direction of the substrate, and a plurality of heat-generating resistors, each having the same shape and electrically connected in parallel between the first conductor and the second conductor on the substrate and a plurality of temperature detection elements for detecting a temperature of the heater and heating an image formed on a recording material by the heater, the plurality of temperature detection elements includes at least two temperature detection elements whose relative positions with respect to the closest heat-generating resistor in the plurality of heat-generating resistors are the same, respectively, the closest heat-generating resistors corresponding to the at least two temperature detection elements are independently controlled.
