PROBLEM TO BE SOLVED: To provide a droplet ejection apparatus capable of suppressing variation in droplet ejection quantity in a droplet ejection head while preventing circuit components becoming large-size. SOLUTION: The droplet ejection apparatus is provided with: a first storing means for storing a driving signal selection data indicating the correspondence between a drive element and the kind of a driving signal to be supplied to the drive element; a second storing means for storing waveform data of each kind of a driving signal; a driving signal generation means for generating each kind of the driving signal; and a driving signal selection means for selecting and supplying one of the driving signals generated by the driving signal generation means for each of the drive elements based on the driving signal selection data. One of the driving signal generation means has current capacity capable of supplying the driving signal to all drive elements, and the driving signal selection date is set in the nozzle having uniform ejection characteristics so that one kind of the driving signal is supplied from the driving signal generation means having the current capacity capable of supplying the driving signal to all drive elements.
