PROBLEM TO BE SOLVED: To suppress generation of a satellite with a simple configuration when discharging a droplet.SOLUTION: After liquid is discharged in a certain discharge direction from a nozzle, the nozzle is accelerated and moved in an approximately vertical direction to the discharge direction to separate a liquid column before the liquid column grows to generate the satellite, thus generation of the satellite is suppressed and the stable droplet is formed to prevent a deterioration of image quality. |
