CONSTITUTION: An ejection cell comprises an N channel drive FET(field effect transistor) 101 for driving a heater resistor 21 having drain connected with one terminal of the heater resistor 21 and source connected with a common reference voltage, e.g. earth. When an ejection pulse is present, the drive transistor 101 is turned on to enable transmission of ejection pulse energy to the heater resistor 21 as a function of the state of conduction data. An ink jet ejection system having decreased number of external interconnections can thereby be fabricated using a low cost NMOS integrated circuit processing.
