Fixing device fixing developing agent image to sheet by electrostatically spraying charged fixing solution

A fixing device for fixing a developing agent image to a recording sheet by electrostatically spraying a charged fixing solution toward the developing agent image on the recording sheet, the fixing device comprising:

• a container for storing the fixing solution;
• a plurality of nozzles in communication with the container and for spraying the fixing solution toward the developing agent image;
• a potential difference generating portion for generating a potential difference between the fixing solution stored in the plurality of nozzles and the recording sheet conveyed at a position separated from the plurality of nozzles;
• and
• a controller controlling a voltage applied to the potential difference generating portion, the controller applying voltage to the potential difference generating portion such that the fixing solution is sprayed from the plurality of nozzles before a leading end of the recording sheet reaches a fixing region, wherein the controller is configured to:
• set the voltage to a first voltage with which the fixing solution is not sprayed from the plurality of nozzles in a standby state;
• and
• set the voltage to a second voltage higher than the first voltage at a prescribed timing before the leading end of the recording sheet reaches the fixing region in print control.
