ABSTRACT:
A liquid jet recording head includes a liquid path communicating with a discharge opening through which a liquid is discharged; a plurality of heating elements disposed in the liquid path, each of the heating elements having a different minimum power requirement for enabling the liquid to be discharged; and electrodes for allowing electric power to be simultaneously supplied to the plurality of heating elements. This invention further provides a liquid jet recording apparatus having a liquid jet recording head constructed in the above-described manner. The power density of each heating element is varied by the application of a drive voltage, thereby enabling stable step control over the gradation of an image recorded without the need for complicated wiring.
