PROBLEM TO BE SOLVED: To provide a fixing device which prevents an image from being peeled off owing to toner refusion on an OHP sheet or being melt-fused on an image of another OHP sheet by reducing heat energy received when normal paper as a split sheet discharged after image formation on an OHP sheet is passed through a fixing process. SOLUTION: An image forming device is equipped with a heat roller fixation type fixing device 80 which fixes a toner image formed on a transfer material 17a on the transfer paper 17a by heating the image and has a function of discharging normal paper through the fixing device 80 without forming any image after passing a sheet for OHP projection and changes fixation conditions when the normal paper is passed after the toner image is fixed on the sheet for OHP projection by the fixating device 80. |
