PROBLEM TO BE SOLVED: To provide a driving apparatus for an inkjet head capable of decreasing differences of delivering speeds of respective ink droplets when the ink droplets are continuously delivered without applying a boost pulse electric voltage and without introducing complication of controlling, and thereby capable of obtaining a good quality of printing without lengthening a driving period. SOLUTION: When a plurality of the ink droplets are continuously delivered, a plurality of driving pulse electric voltages are impressed on an actuator Z1. Among respective driving pulse electric voltages, the levels of the driving pulse electric voltages of specified number from the beginning are set higher than the levels of the remaining driving pulse electric voltages.
