Abstract:
A liquid discharging head is appropriately driven to effectively prevent a satellite from being generated irrespective of conditions such as a property of a discharge liquid or a head structure. The liquid discharging head is driven using volume variation in a manner that a liquid extending in a column shape at the time of separating a liquid droplet (main droplet) is gradually thickened from the separation portion to a discharge port, and that the liquid protrudes from the discharge port during a period where the length of the liquid extending in the column shape is shortened after the droplet is separated. Accordingly, it is possible to effectively prevent a liquid column from further being separated after the main droplet is separated, and to restrict the satellite from being generated, irrespective of conditions such as the property of the discharge liquid or the head structure.
