An image forming apparatus for forming an image on a recording medium by heating the medium having ink applied to its surface layer by a heater device, thereby to fix the ink applied to the surface layer to a fixing layer of the recording medium. A heating controlling section (78) for controlling the heater device (4) includes a fixing behavior evaluating means (9) for evaluating a fixing behavior of the ink to the fixing layer and then outputting a control amount to the heating controlling section (78) for controlling the heater device (4). The fixing behavior evaluating means (9) includes such functions as a sublimation degree evaluating function for evaluating a sublimation degree of the ink in the recording medium (1), a function for evaluating surface temperature distribution of the recording medium or a transferred energy evaluating function for evaluating transferred energy received by each area of the recording medium (1). |
