An apparatus for ejecting very small droplets according to the present invention comprises a first ink ejector and a second ink ejector. The first ink ejector is controlled to eject a main droplet and a satellite droplet in accordance with one ink ejection signal such that the main droplet collides with an ink droplet ejected from the second ink ejector. A trajectory of a united droplet, formed by the collision of both droplets, is different from a trajectory of the main droplet, and the united droplet flies toward an in catcher. Only the satellite droplet having very small volume lands on a paper.
