Ink jet recording apparatus

摘要

An ink jet recording apparatus that can perform high velocity printing without printing distortion is realized. In a continuous discharge type ink jet recording apparatus, a unit that suppresses a velocity in the vicinity of a center axis is disposed in a unit that injects ink droplets in which because a velocity in an outer periphery is higher than that in a center of a discharged liquid column, a velocity on a surface of the liquid column becomes quickly high, and a capillary wave that propagates on a surface of the liquid column in a travel direction is quickly amplified because the velocity becomes quickly a velocity suitable for droplet breakup, the droplet breakup is quickly generated, and the droplet breakup is surely generated within a charging electrode located next to the nozzle. As a result, an ink jet recording apparatus stable in printing quality performance is provided.
