PROBLEM TO BE SOLVED: To provide an image forming device capable of preventing the generation of fixing failure and shortening the time required by the starting of image forming operation after paper clogging is treated. SOLUTION: When paper clogging is generated, the control of a heater is stopped S1, and time elapsed from a copy impossible state is measured with a timer S2. When paper clogging is treated and a device becomes a copy operation ready state, measurement with the timer is finished, the lighting of a heater is started S3 to raise the temperature of a fixing roller whose temperature is lowered. In this time, time tB is judged, S5, and if to is within the constant time to, forward rotation operation is not conducted S6 when a device main body is moved from the copy ready state to a copy possible state, and if tB exceeds tC, forward rotation operation is conducted S7), and after that, the fixing temperature is controlled so as to keep T1 . |
