An image forming device (1) capable of performing both-side printing, statically transferring, by application of a transfer voltage, an unfixed image formed on an image carrier (11) to a recording sheet when passing through a transfer position (46), and then thermally fixing the unfixed image when the recording sheet passes through a fixing position (53) where a heating rotating body (51) is disposed. The image forming device (1) acquires an index value of a water content at each of a plurality of sheet-passing-direction positions of the recording sheet having undergone thermal fixing of an unfixed image statically transferred onto a first side thereof, and controls, for each of the positions, a transfer voltage applied for statically transferring an unfixed image onto a second side of the recording sheet, so that the lower the water content indexed by the index value of the position, the greater an absolute value of the transfer voltage. |
