An ink-jet head having a plurality of discharge openings for discharging ink therefrom, and an ink chamber which communicates with the discharge openings is driven so as to achieve stable ink discharging operation, by preventing meniscus vibration caused by resonance of the meniscus surface of the ink at the discharging openings in response to the pressure wave which is produced in the ink chamber due to changes in pressure in the ink chamber resulting from the ink discharging operation. More specifically, the driving timing of the ink-jet head is adjusted in a time division manner within a predetermined driving period.
