ABSTRACT:
A liquid jet recording head which is used for generating bubbles in a writing liquid of a liquid chamber and discharging droplets of the writing liquid to a recording sheet in an ink-jet printer. The liquid jet recording head includes an orifice from which the writing liquid is discharged, a liquid discharge path leading to the orifice, the orifice communicating with the liquid chamber. The liquid jet recording head further includes a plurality of energy generating elements for generating energy to produce the bubbles in the writing liquid, the plurality of energy generating elements being provided within the liquid chamber and corresponding to a single orifice. Each of the energy generating elements has an energy transmitting surface which is approximately perpendicular to the liquid discharge path, and one or more combinations of the energy generating elements which are independently driven by the drive control mechanism to allow gradation recording on the recording sheet.
