ABSTRACT:
A recording apparatus is provided with a recording head including an element substrate having plural recording elements for recording and a temperature detecting element for detecting the temperature of the element substrate, and a temperature detecting unit for detecting the ambient temperature. The temperature detecting element is adapted to receive a predetermined signal and to output an output signal corresponding to the temperature of the element substrate. The recording apparatus further includes a correction circuit for correcting the signal to be given to the temperature detecting element, based on the output signal of the temperature detecting element and the output signal of the temperature detecting unit, in such a manner the output signal of the temperature detecting element at a certain temperature becomes a predetermined output.
