Image forming device, and image forming method

An image forming device, comprising:

• a head comprising a nozzle that discharges an electrically-conductive recording liquid in accordance with a driving signal;
• an intermediate transfer body on which the recording liquid is applied, wherein at least a surface of the intermediate transfer body is electrically conductive;
• a voltage apply unit that applies a voltage between the intermediate transfer body and the head, so as to decompose the recording liquid by electrolysis, wherein the recording liquid is in a state in which the recording liquid temporarily bridges between the head and the intermediate transfer body;
• a transfer unit that transfers an image onto a recording materials, wherein the image is formed of the recording liquid and supported on the intermediate transfer body;
• and
• a discharging control unit that generates the driving signal causing the recording liquid to be discharged from the nozzle, wherein the discharging control unit generates the driving signal so that a meniscus is placed outside the nozzle during a time interval in which the recording liquid is in the state,
• wherein the discharging control unit generates, a first driving signal that causes the recording liquid to be in the state and a second driving signal that causes the recording liquid to be additionally discharged from the nozzle during the state, and
• wherein the discharging control unit sets a time interval between the first driving signal and the second driving signal so that the time interval becomes an integral multiple of an oscillation period of the meniscus at the nozzle.
