An image forming apparatus with a voltage applying unit between a recording head and an intermediate transfer drum is capable of activating polyvalent metal ions inactivated in advance in jetted recording liquid without liquid activators independent of the recording liquid for sufficient flocculation on the drum. When the jetted recording liquid temporarily bridges the head and the drum, electrolysis of the recording liquid by the voltage applied instantly leads to generation of hydrogen ions on the drum, which triggers a sequence of reactions in the recording liquid of activation of polyvalent metal ions, cross-link between the activated polyvalent metal ions and anionic polymer, and increase in viscosity on the drum.

Image forming apparatus and recording liquid

An image forming device includes a head including a nozzle that discharges an electrically-conductive recording liquid in accordance with a driving signal; an intermediate transfer body on which the recording liquid discharged by the head is applied; a voltage apply unit that applies a voltage between the intermediate transfer body and the head, so as to decompose the electrically-conductive recording liquid by electrolysis; a transfer unit that transfers an image supported on the intermediate transfer body onto a recording material; and a discharging control unit that generates the driving signal that causes the electrically-conductive recording liquid to be discharged from the nozzle. The discharging control unit generates the driving signal so that a position of a meniscus is placed outside the nozzle during a time interval in which the recording liquid temporarily bridges between the head and the intermediate transfer body.
