A recording method ejects ink by thermal energy produced by a heat generating element of a recording head in response to a drive signal. The method includes the step of controlling an amount of ejection of the ink by a temperature control for the recording head including at least heating of the recording head, when a temperature of the recording head is not higher than a predetermined first temperature. The method further includes the steps of controlling the amount of ejection of the ink by changing a waveform of the drive signal for ejecting ink in accordance with the temperature of the recording head when the temperature of the recording head is higher than the first temperature and not higher than a second temperature, and fixing the waveform of the drive signal when the temperature of the recording head is higher than the second temperature.
A recording method in which ink is ejected by thermal energy produced by a heat generating element of a recording head in response to a drive signal, said method comprising the steps of:
An ink jet recording apparatus wherein recording is effected using a recording head having a heat generating element generating thermal energy for ejecting ink, said apparatus comprising:
A method of controlling an amount of ejection of ink in an ink jet system wherein the ink is ejected by thermal energy produced by a heat generating element of a recording head in response to a drive signal, said method comprising the steps of:
An ink jet recording apparatus wherein recording is effected using a recording head having a heat generating element generating thermal energy for ejecting ink, said apparatus comprising:
