ABSTRACT:
A nozzle is supplied with pressurized ink, and is given mechanical vibrations, thereby to generate large-diameter and small-diameter ink droplets successively and alternately from an ink column produced from the front end part of the nozzle. Charging and deflecting electrodes are disposed which charge one of the large-diameter and small-diameter ink droplets developed from the foremost end of the ink column, in response to a recording signal and which exerts a deflecting force on the charged ink droplet simultaneously with the development of the large-diameter and small-diameter ink droplets. Thus, the flight orbits of the charged ink droplets necessary for the recording of an ink-jet recording device and the ink droplets unnecessary for the recording can be separated immediately after the development of the ink droplets.
