PROBLEM TO BE SOLVED: To provide an image forming device capable of always obtaining the excellent quality transfer image by means of heat controlling so that the temp. of a transferring roller becomes to the specific temp. SOLUTION: This device is, composed so as to transfer the toner image on a photosensitive drum 12 onto an recording paper by arranging a transferring roller 16 in freely rotationally opposing with respect to the photosensitive drum 12, holding a paper sheet in close contact with the photosensitive drum 12 surface by the impressed transferring roller 16, and applying a prescribed voltage on the close contact section. In this case, the temp of the transferring roller 16 is approximately kept as specified by heating the transferring roller 16 with a heater roller 25 while detecting the temp. of the heated roller 16 with the temp. sensor 27, and performing feed back controlling the heater roller 25 based on the detecting value. Then, resistance value of the transferring roller also becomes to the specific value. |
