It is an object of the present invention to provide an ink jet printing apparatus which sufficiently heats a head even in a low-temperature environment, which enables a proper image to be printed by stably ejecting ink, and which can be inexpensively and simply constructed. According to the present invention, if the detected temperature of a printhead is lower than a first heating threshold temperature higher than the first heating threshold, a heating mode in which the printhead can be heated is set before a printing operation. Further, when the heating mode is set and the detected temperature of the printhead is lower than the heating threshold temperature, a heating unit heats the printhead. Consequently, even in a low-temperature environment, the heating operation keeps ink good and suitable for printing.
