Patent ID: 7059710

Claim:
A method for forming an ink-jet image, comprising the steps of: (a) ejecting droplets of an ink through ink-nozzles of an ink-jet head of an ink-jet recording apparatus, the ink-jet head being provided with: (i) a plurality of ink chambers having the ink-nozzles, each ink chamber having a dividing wall between adjacent ink chambers, the dividing wall containing an actuator which deforms in response to applied voltages to the adjacent ink chambers; and (ii) a common ink tank which communicates with the ink chambers respectively, the ink-jet recording apparatus being provided with a driving signal generator for continuously generating multiple driving signals applied to the actuator, the driving signal generator producing: an expansion pulse which expands a volume of the ink chamber by deforming the actuator contained in the dividing wall of the ink chamber; a shrinkage pulse which compresses the volume of the ink chamber by deforming the actuator; and a predetermined quiescent period between the expansion pulse and the shrinkage pulse, the droplets of the ink being ejected on a recording media from the ink-nozzles by a repeated expansion and shrinking of the ink chamber, and the quiescent period being regulated so as to decrease the cross talk among the ink chambers adjacent to each other, (b) hardening the droplets of the ink ejected on the recording media via irradiation of an actinic ray, wherein a volume of each of the droplets of the ink is between 2 to 15 pl, and the ink contains a radical polymerization monomer and a radical initiator.
