摘要： An ink jet recording apparatus includes: a head body provided with a nozzle and a pressure chamber; an actuator including a piezoelectric element and an electrode for applying a voltage across the piezoelectric element; and a driving circuit for supplying a driving signal to the electrode of the actuator. The driving circuit always supplies an auxiliary pulse signal in every printing cycle. When ink is to be discharged, the driving circuit supplies, after the auxiliary pulse signal is supplied, an ink discharge pulse signal for driving the actuator so that the ink is discharged and so that an ink meniscus vibration in the nozzle is resonant with that caused by the auxiliary pulse signal.

摘要： An ink discharging device includes arrayed nozzle holes and corresponding ink flow paths leading thereto. An electrode is provided between the adjacent ink flow paths in such a manner as to be exposed to both of the adjacent ink flow paths so that each electrode works as a common electrode for both of the adjacent ink flow paths. By energizing a conductive ink between the electrodes within the corresponding ink flow path, a portion of the conductive ink is discharged through the corresponding nozzle hole.

摘要： An electrostatic ink jet recording apparatus which includes a first electrode which is a recording electrode, a second electrode which is a collecting electrode, and a third electrode which is a common electrode. A potential difference is selectively given between the first and second electrodes for selectively attracting toner particles by electrostatic force. The ink is then ejected and traveled onto a recording medium for printing by applying potential to the third electrode. This configuration prevents dispersion of toner particles while applying ejection signals, enabling to suppress ejection failure and unstable discharge even in high frequency prints.
