PROBLEM TO BE SOLVED: To provide an image forming device capable of shortening image forming processing time and saving power consumption by making the number of switching times of the fixing temperature of a fixing means as few as possible. SOLUTION: In the case of successively and continuously supplying plain paper and OHP sheets to a photoreceptor by the 1st number of sheets and the 2nd number of sheets respectively, a cassette and a multi-feeder paper supply tray supply the OHP sheets to the photoreceptor by selecting it when the fixing temperature T of a fixing device reaches a threshold Tc set to be equal to or above fixing temperature To for performing fixation on the plain paper and equal to or under the fixing temperature Tp for performing fixation on the OHP sheet so that reaching time to the fixing temperature Tp may be equal to that to the fixing temperature To, and supply the plain paper to the photoreceptor by selecting it when the fixing temperature T does not reach the threshold Tc. |
