Recording apparatus and recording method

A recording apparatus including a recording head, the recording head including a plurality of recording devices containing ink, a heating device, and a detection device, the recording devices each generating energy for ejection of the ink, the heating device heating the ink in a vicinity of recording devices, and the detection device detecting a temperature in the vicinity of the recording devices, the recording apparatus comprising:

• an acquisition unit configured to acquire information relating to the temperature detected by the detection device;
• a determination unit configured to determine whether the temperature or a first temperature threshold is higher;
• a decision unit configured to decide an upper limit of driving power of the heating device, based on a determination result of the determination unit;
• a recording control unit configured to drive the recording devices to control a recording operation;
• and
• a heat control unit configured to drive the heating device to control a heating operation during the recording operation, based on the temperature detected by the detection device and a second temperature threshold that is higher than the first temperature threshold,
• wherein the heat control unit drives the heating device to cause the driving power to be lower than the decided upper limit indicated by the representative temperature related information, and
• wherein the decision unit decides the upper limit (i) so as to increase the upper limit in a case where the determination unit determines one time that the temperature is lower than the first temperature threshold, and (ii) so as to decrease the upper limit in a case where the determination unit consecutively determines N(N≥2) times that the temperature is higher than the first temperature threshold.
