PROBLEM TO BE SOLVED: To provide an image forming apparatus that appropriately exerts control so that, when rotors in a fixing unit are stopped during a standby state and temperature control is exerted so that predetermined standby temperature is obtained, the temperatures of the rotors are appropriately controlled so as not to rise excessively high but so as not to drop unnecessarily low. SOLUTION: The image forming apparatus includes a determining means S10 for determining whether to shift to the standby state from a fixing state, the standby state being the state in which rotations of the pair of rotors are stopped and temperature control is exerted so that at least one of the rotors reaches predetermined standby temperature, and the fixing state being the state in which the pair of rotors are rotated and temperature control is exerted so that at least one of the rotors reaches a fixing temperature changed according to a setting; and fixing control means S11 to 14 for rotating the pair of rotors prior to the temperature control for the standby state when shift is necessary, and controling the temperature of at least one of the rotors so that the fixing temperature falls within a predetermined shifting temperature range in which the fixing temperature is lower than the highest one but higher than the lowest one.
