PROBLEM TO BE SOLVED: To obtain a method for driving a liquid droplet ejection head which can largely change an ejection amount without lowering driving frequency for printing, a liquid droplet ejection head and a liquid droplet ejection device.SOLUTION: From a state where a diaphragm 4 partially abuts on a fixed electrode 5 by application of drive voltage V2 to an electrostatic actuator, a driving control circuit 41 applies drive voltage V3 obtained by increasing a voltage value from a voltage value of the drive voltage V2, to extend an abutting area of the diaphragm 4 on the fixed electrode 5, whereby an ink extrusion part 12 is cut off and ink is ejected as an ink drop 13 to the outside. |
