Abstract
According to one embodiment, a driving device applies an ejection pulse signal that deforms a partition in such a way that an ink drop is ejected from a nozzle and an auxiliary pulse signal that deforms the partition to such an extent that an ink drop is not ejected from the nozzle, as a drive signal for providing a potential difference between electrodes, to an inkjet head at different timings so that the two pulse signals are not applied simultaneously. A constraint on output of the auxiliary pulse signal is significantly relaxed.
