PROBLEM TO BE SOLVED: To provide a liquid injecting device having a configuration for injecting a plurality of liquid droplets within a unit cycle and integrating the liquid droplets until they hit a hitting target and capable of suppressing a flying speed difference between the liquid droplets after the integration. SOLUTION: A preceding drive pulse Na is set so that when ink droplets are simultaneously injected from a plurality of nozzles adjacent to one another, flying speed of the ink droplets on the central side in the nozzle row direction out of the respective injected ink droplets is higher than that of the ink droplets on the end side in the nozzle row direction. A subsequent drive pulse Nb is set so that flying speed of the ink droplets on the end side out of the respective ink droplets simultaneously injected from the plurality of adjacent nozzles is higher than that of the ink droplets on the central side.
