<P>PROBLEM TO BE SOLVED: To easily and accurately perform grouping of ejection nozzles according to the level of an ejection amount, and also, easily and accurately determine an appropriate driving voltage for each of the groups. Ž<P>SOLUTION: A driving voltage determination method for a liquid droplet ejection head includes: a landing dot formation step of forming a plurality of landed dots on a measurement sheet 71 by performing ejection-driving of a plurality of the ejection nozzles 21; an area measurement step of measuring the area of the plurality of formed landed dots; a grouping step of grouping the plurality of ejection nozzles 21 into two or more groups on the basis of the size of the measured area of the landed dots; an ejection weight measurement step of performing ejection-driving of all the ejection nozzles 21 of each of the groups with respect to the receiving container of receptacle 62 of a weight measurement unit 58, and measuring the ejection weight of a functional liquid for each of the groups; and a driving voltage determination step of determining the appropriate driving voltage for each of the groups on the basis of the ejection weight measured for each of the groups.
