Ink jet driving apparatus and ink jet driving method

When a diameter of a hole at an exit of a nozzle is expressed as D (μm) and a distance between a position in a circulation flow path part on a side thereof closest to the exit and the exit is expressed as N (μm) in an ink jet driving apparatus, N≤3.47D is satisfied. During non-ejection, a driving co...

Zusammenfassung:	When a diameter of a hole at an exit of a nozzle is expressed as D (μm) and a distance between a position in a circulation flow path part on a side thereof closest to the exit and the exit is expressed as N (μm) in an ink jet driving apparatus, N≤3.47D is satisfied. During non-ejection, a driving control unit generates a driving signal for withdrawing ink from the exit of the nozzle to a side of a pressure chamber through a distance of 0.16N or more and 0.555D or less, and for causing the ink meniscus to oscillate, and applies the driving signal to a driving element.
