Title: Ink jet recording method and apparatus for driving recording head based onhead temperature

Abstract: A recording method ejects ink by thermal energy produced by a heatgenerating element of a recording head in response to a drive signal. Themethod includes the step of controlling an amount of ejection of the inkby a temperature control for the recording head including at least heatingof the recording head, when a temperature of the recording head is nothigher than a predetermined first temperature. The method further includesthe steps of controlling the amount of ejection of the ink by changing awaveform of the drive signal for ejecting ink in accordance with thetemperature of the recording head when the temperature of the recordinghead is higher than the first temperature and not higher than a secondtemperature, and fixing the waveform of the drive signal when thetemperature of the recording head is higher than the second temperature.
