Abstract: Provided is a driving device of a liquid droplet discharging head including a driving unit that drives a liquid droplet discharging head which includes plural nozzles, which discharge an ultraviolet ray curable liquid, as liquid droplets, the ultraviolet ray curable liquid being cured by being irradiated with ultraviolet rays, and a control unit that controls the driving unit so that, among the plural nozzles, a draw-in driving signal for drawing the liquid in from a discharge surface of non-discharge nozzles of the liquid droplets is supplied to the non-discharge nozzles while ultraviolet rays from an ultraviolet ray light source, which irradiates liquid droplets discharged from the liquid droplet discharging head with ultraviolet rays, are being emitted.
