摘要：
An ink is ejected at the same timing from ejection orifices in a number corresponding to an ink quantity 7% or less of an ink quantity ejected from all the ejection enabled ejection orifices of a plurality of ejection orifices of a recording head, and the ink ejection period from all the ejection enabled ejection orifices is set to be 70% or more of the driving period. Since the quantity of an ink ejected per unit time is minimized, and the negative pressure level generated in a common ink chamber can be set to be closest to normal pressure, the amplitude of a refill oscillation is minimized to stabilize ejection, and the driving frequency can be further increased.
