Abstract
A recording head that includes a pressure chamber filled with ink and a piezoelectric element changing pressure inside the pressure chamber, and that ejects ink from the nozzle according to the change in the pressure inside the pressure chamber. A control unit controls the piezoelectric element and performs ejection driving for ejecting the ink from the nozzle or micro-vibration driving for micro-vibrating a liquid surface inside the nozzle to an extent at which the ink is not ejected from the nozzle; and performs a flushing operation of an ejection amount according to a number of times of micro-vibration driving in a driving period, in a preparation period after the driving period has passed.
