Claim Text:
1. An image recording apparatus comprising: a recording head including at least a substrate, a recording element array in which a plurality of recording elements that are arranged on the substrate in a predetermined direction and generate thermal energy for ejecting ink of a predetermined color, a first detection element that detects a temperature in a vicinity of the recording element at a first position in the predetermined direction in the recording element array, a second detection element that detects a temperature in a vicinity of the recording element at a second position that is different from the first position in the predetermined direction in the recording element array, and a heating element that performs heating of ink in the vicinity of the recording elements at the first position and the second position among the plurality of the recording elements arranged in the recording element array; and a control unit that controls the heating by the heating element on the basis of the temperatures detected by the first and second detection elements, wherein the control unit controls the heating by the heating element in a manner that the heating by the heating element is executed in a case where a temperature difference between the temperature detected by the first detection element and the temperature detected by the second detection element is higher than a first threshold.
