PROBLEM TO BE SOLVED: To uniform a discharge amount while using a liquid droplet discharge head of a simple configuration. SOLUTION: In the driving method of the liquid droplet discharge head, the liquid droplet discharge head is provided with a plurality of discharge units discharging a liquid body. In a sequence in which discharge amounts obtained by driving the plurality of discharge units by predetermined driving signals are arranged in order of their magnitude, each of a plurality of groups is constituted of discharge units corresponding to continued elements, the plurality of discharge units are divided into a plurality of groups G1 to G4 by using weighted averages based on discharge amounts of the plurality of discharge units, a plurality of driving signals adjusted for each group of the plurality of groups G1 to G4 are selected and supplied to the plurality of discharge units so that statistics of discharge amounts obtained by performing driving by the predetermined driving signals in each of the plurality of group G1 to G4 are brought close to a setting value of the discharge amount. Thus the discharge units are driven. COPYRIGHT: (C)2009,JPO&INPIT
