<p>An image forming apparatus includes: a curl correction device (40) which corrects curl generated in a recording medium (P) having passed through a fixing device (30, 34, 37); a temperature/humidity sensor unit (41) which is installed in a conveying path between the fixing device (30, 34, 37) and the curl correction device (40), and detects and outputs temperature and humidity near a surface of the recording medium (P); a calculation unit (203) which calculates temperature and moisture content of the recording medium (P) from the temperature and humidity output values output from the temperature/humidity sensor unit (41), and calculates curl correction efficiency of the curl correction device (40) from the temperature and moisture content of the recording medium (P); a control value determination unit (204) which determines a control value to perform a curl correction in the curl correction device (40), based on the curl correction efficiency calculated by the calculation unit (203); and a control unit (206) which controls the curl correction device (40) by the control value.</p> |
