Driving device for liquid droplet jetting device, liquid droplet jetting device, image forming apparatus, and computer readable medium

摘要

A driving device for a liquid jetting apparatus includes an application unit and a controller. The application unit generates and applies a first voltage of a first waveform to a first pressure generating unit and generates and applies a second voltage of a second waveform to the second pressure generating unit to jet a liquid droplet outside a nozzle after pulling liquid inside the nozzle. The second waveform includes at least one of a third waveform corresponding to a jetting angle for changing a jetting direction from a reference direction by deforming a liquid level of liquid pulled inside the nozzle in a direction of pushing the liquid level outside the nozzle, or a fourth waveform corresponding to a jetting angle for changing the jetting direction from the reference direction by deforming the liquid level of liquid pulled inside the nozzle in a direction of further pulling the liquid level.
