PROBLEM TO BE SOLVED: To provide a setting method of a drive signal which can suppress a variation in liquid droplet ejection amount in a liquid droplet ejection head while preventing an enlargement of the size of circuit components. SOLUTION: The driving method of the liquid droplet ejector which ejects liquid droplets from nozzles by supplying the drive signals generated by a plurality of drive signal generating means to driving elements set for every plurality of the nozzles has the process A of setting one corresponding drive signal generating means for each of the plurality of nozzles, and the process B of ejecting the liquid droplets by supplying the drive signals generated by the drive signal generating means set in the process A to the driving elements. In the process A, the number of the nozzles set for each drive signal generating means is set not to exceed a permissible maximum number of nozzles preliminarily set according to a current capacity of each drive signal generating means.
