Abstract
An ink jet recording head wherein a nozzle jetting ink droplets is structured of a plurality of ink jet ports , and the length l [m] of an ink jet port and pitch P [m] are set to satisfy the conditions l >1.2 V /A and P >1.4 d (where V is the volume of ink droplets that are jetted from one individual ink jet port [m ], d is diameter of an ink droplet [m] and A is the area of a nozzle opening [m ]); wherein the fusion phenomena of a meniscus at the rear surface of a nozzle after ink is jetted can be suppressed; and wherein the effect of a multi-port nozzle enabling re-fill time to be reduced is utilized. Further the fusion phenomena of ink jet droplets in flight after being jet expelled from a multi-port nozzle can be suppressed enabling superior quality images to be recorded.
