Liquid ejecting head drive method and liquid ejection device

A liquid-ejecting apparatus comprising:

• a piezoelectric body;
• and
• a pressure chamber that changes volume and thus ejects liquid through application of voltage to the piezoelectric body,
• wherein a driving waveform applied to said piezoelectric body during the liquid ejecting operation based on signals output from a control unit, comprises a high potential period in which a voltage exhibiting an electric field strength exceeding the coercive electric field of said piezoelectric body is applied, and a reverse potential period in which a voltage such that the potential becomes of the opposite polarity to the polarity in said high potential period or the potential becomes zero is applied,
• wherein the voltage applied in said reverse potential period is a voltage exhibiting an electric field strength of at least the coercive electric field of said piezoelectric body, and
• wherein the time period between when the absolute value of the voltage applied in said reverse potential period starts to drop from a maximum value and when the absolute value of the voltage applied in said high potential period reaches approximately a maximum is not more than 2 μs.
