Abstract
In a heater including a plurality of first temperature detection elements that are arranged at predetermined intervals in a longitudinal direction of a substrate and respectively output temperature signals individually, and a plurality of second temperature detection elements that are arranged at predetermined intervals in positions that differ from the positions of the first temperature detection elements in a lateral direction that is orthogonal to the longitudinal direction but correspond to the positions of at least some of the plurality of first temperature detection elements in the longitudinal direction, and that output a single temperature signal obtained by adding individual temperature signals together, the individual temperature signals included in the single temperature signal are acquired on the basis of the plurality of temperature signals output by the plurality of first temperature detection elements and the single temperature signal.
