The two kinds of fluids are mixed together to form a fluid mixture to be ejected toward a recording medium. A minimum distance d between the first and second discharge openings of the metering and ejecting nozzles is in the range of 0.ltoreq.d.ltoreq.5.sqroot. (S1) where S1 stands for an opening area of the first discharge opening of the ejecting nozzle.
