Abstract
An ink jet recording device for jetting an ink droplet from a free surface of an ink material includes: an ink container for containing the ink material and providing the free surface of the ink material therein; a vibrating member for providing a vibrating energy to the free surface of the ink material by contacting thereto at an interface portion between the free surface of the ink material and the ink container, wherein the vibrating means surrounds the free surface so that the vibrating energy is concentrated at one specific portion on the free surface of the ink material in order to jet the ink droplet therefrom; and an actuating system for actuating the vibrating member. An ink jet recording method using the same is also disclosed.
