Abstract

An ink-jet recording apparatus includes an ink-jet head which includes a plurality of nozzle openings, a plurality of independent ejection chambers respectively correspondingly communicatd with the nozzle openings, diaphragms respectively correspondingly formed in the ejection chambers partly on at least one side walls of the ejection chambers, a plurality of driving elements for respectively correspondingly driving the diaphragms, and a common ink cavity for supplying ink to the plurality of ejection chambers, so that upon application of electric pulses to the plurality of driving means, the driving elements respectively correspondingly distort the diaphragms in the direction of increasing the respective pressures in the ejection chambers to eject ink drops from the nozzle openings onto recording paper, wherein the respective driving elements are constituted by electrodes for respectively correspondingly distorting the diaphragms by electrostatic force, the electrodes being formed on a substrate.
