Present invention provide a driving device of a liquid discharging head, a liquid discharging apparatus, and an ink jet recording apparatus that are capable of realizing a desired dot shape by suppressing the generation of the meniscus without sacrificing the discharge efficiency or the landing accuracy. According to the present invention, in a case where discharging is performed a plurality of times in one recording period, and one pixel is recorded by using a plurality of droplets, by configuring the wave height change time of a rear-end side wave height change part of the final pulse of a plurality of discharge pulses to be equal to or longer than a quarter of the resonant period Tc and configuring the pulse width of the plurality of discharge pulses to be a half of the resonant period Tc.
