摘要： The invention intends to maintain a constant ink discharge amount among the recording heads, even in case a total pulse width of pulse voltages applied to heat generating resistors. For this purpose, a rank table is prepared in such a manner, even in a situation where a total pulse width of the pulses applied to the heat generating resistor is 3 μs or less whereby the ink discharge amount decreases with a decrease in the total pulse width, that a maximum reached temperature on the surface of the heat generating resistors at the application of a preheat pulse becomes higher with a decrease in the resistance of a rank resistor, and a pulse width P1 on the rank table is made longer thereby compensating a decrease in the ink discharge amount with a decrease in the total pulse width and maintaining a constant ink discharge amount.

摘要： A recording head comprises a plurality of recording elements for performing recording; a driving circuit for driving the plurality of recording elements; and a predetermined voltage generating circuit for generating a predetermined voltage to be applied to the plurality of recording elements from voltage supplied from outside. With the head thus structured, a desired voltage is generated in the interior of the head by use of the predetermined voltage generating circuit for performing recording, thus making it possible to prevent the voltage drop which may take place if the voltage is supplied from outside through a cable, as well as to prevent the durability of the heat generating elements from being damaged due to noises. It also becomes possible to set the voltage to be applied to the recording elements at an optimal value corresponding to the discharge voltage, hence stabilizing ink discharges efficiently.
