Abstract: An apparatus includes a liquid ejecting head capable of ejecting liquid from a plurality of ejection ports by driving a plurality of ejection energy generation elements corresponding to the plurality of ejection portions. The apparatus includes a wiping mechanism capable of wiping an ejection port face in which a plurality of ejection ports is arranged in the liquid ejecting head. The ink ejection from the plurality of ejection ports is performed in a manner of a plurality of divisions. A time interval from a last wiping to a next wiping is adjusted according to an interval of the ejection energy generating elements corresponding to an adjacent ejection port.
