Zusammenfassung:	A liquid droplet ejection apparatus for use in the present liquid droplet ejecting method comprises a base member 30 and a piezoelectric/electrostrictive element 41, the interior of the base member being provided with a pressurizing chamber 30b and an ejection opening 30d. When the interval from the last pressurizing operation to the current pressurizing operation is longer than a predetermined time, applied voltage to the piezoelectric/electrostrictive element is increased at a first voltage increase rate so that liquid within the pressurizing chamber is pressurized for ejection at a first pressurizing increase rate. When the interval from the last pressurizing operation to the current pressurizing operation is shorter than the predetermined time, the applied voltage is increased at a second voltage increase rate which is smaller than the first voltage increase rate so that the liquid is pressurized for ejection at a second pressurizing rate which is relatively small. This ensures proper pressurization on the liquid whose viscosity increases with the lapse of time, achieving proper ejections.
