Disclosed are a droplet ejection device and method using an electrostatic field. The droplet ejection method includes: setting a separate electric field direction in each of a plurality of nozzles; supplying one of ink and ink containing particles to each nozzle; and forming and ejecting a plurality of separate ink droplets. The droplet ejection device includes a deposition part having electrode layers and insulating layers deposited toward a nozzle. Therefore, it is possible to readily perform droplet ejection without a heater or diaphragm vibration device. In addition, it is possible to reduce impact applied to the ink and obtain good print quality, since the ink is ejected using the electrostatic field.
