ABSTRACT:
A polycrystalline silicon layer which serves as a heating resistor is laid on a Si substrate, whereby a heating area 25 and a low-resistance area 26 are formed. In this event, the area of the heating area 25 is set according to the physical properties of ink squirted from a corresponding nozzle. As a result, the amount of ink droplet to be squirted becomes an optimum value, and the quality of an image is improved. Further, the heating area 25 is formed such that the resistance of the heating area becomes larger as the area of the heating area becomes smaller. Eventually, the amounts of energy per unit area of the heating areas become equal to each other, and ink-jet nozzles can be actuated using the same drive pulse.
