Abstract
A printing apparatus and temperature detecting method can accurately obtain temperature of a printing element substrate and output a high-quality image at high resolution and high speed. For this purpose, a first temperature sensor outputting signals through a first output line and a second temperature sensor outputting signals through a second output line that is longer than the first output line are provided on the printing element substrate. In addition, a switch between the case of using detected temperatures obtained from both of the first temperature sensor and the second temperature sensor to calculate the temperature of the printing element substrate, and the case of using only the detected temperature obtained from the first temperature sensor to calculate the temperature of a printing element substrate is made. On this basis, inaccurate temperature of a printing element substrate due to noise can be avoided.
