Abstract
A CPU serving as a counting unit counts the cumulative number of times a driving pulse is applied to a piezoelectric vibrator. A driving signal generation unit is able to generate an aging driving pulse set by a driving parameter to the extent that ink is not ejected from a nozzle and performs an aging process of driving the piezoelectric vibrator using the aging driving pulse set by a driving parameter in accordance with a cumulative number of applications in a region outside an ejection region on a recording medium.
