Abstract:
An ink jet recording head includes a plurality of ejection outlets for ejecting liquid; individual liquid chambers communicating with the plurality of ejection outlets; ejection energy generating elements, provided correspondingly to associated ones of the individual liquid chambers, for generating energy for ejecting the liquid; a common liquid chamber for supplying the liquid to the plurality of individual liquid chambers; and communicating paths constituting flow paths for communicating associated ones of the individual liquid chambers and the common liquid chamber with each other. At least adjacent ones of the flow paths have communicating positions, at different portions as seen in a direction perpendicular to a direction of ejection of the liquid through the ejection outlets, with said common liquid chamber.
