ABSTRACT:
In the recording method and apparatus, ink is ejected by thermal energy produced by a heat generating element of a recording head in response to application of driving signals thereto, the driving signals being of plural waveforms including a fixed waveform. The method includes the steps of detecting a temperature of the recording head and applying the driving signals to the heat generating element of the recording head. The waveforms of the driving signals are changed in accordance with the temperature of the recording head when the temperature of the recording head is below a predetermined level, and the waveforms of the driving signals comprise the fixed waveform when the temperature of the recording head exceeds the predetermined level.
