摘要：
In an image recording apparatus having a recording head, recording may be interrupted (for example, to permit transfer of new image data after a predetermined amount of recording is performed). Recording quality is maintained by compensating for the change in head temperature which occurs during the interruption. This is done by detecting the temperature of the recording head and/or counting the interruption time, and driving the recording head in a stand-by mode or correcting the image signal in accordance with the temperature difference between interruption and resumption of recording.
