| titleOfInvention | Droplet discharge head driving method, droplet discharge head, and image forming apparatus |
| abstract | An object of the present invention is to ensure stable ejection performance at low cost by suppressing a decrease in displacement characteristics of a thin film piezoelectric actuator over time. A droplet discharge head using an actuator made of PZT outputs a voltage of either positive or negative polarity via a drive IC that applies a pulse-shaped voltage to the upper electrode and a DC voltage to the lower electrode. Then, a drive waveform is applied to the piezoelectric element to eject a droplet. Between the drive waveform and the next drive waveform, as a recovery waveform, a voltage portion that forms a recovery electric field having a polarity opposite to that of the drive electric field by the DC voltage applied to the upper electrode and the upper electrode, and a meniscus natural period A pulse-shaped voltage that does not resonate is applied.
