摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of suppressing the deterioration of image quality in constitution for heating an object to be heated by heat exchange by a coolant. SOLUTION: In the image forming apparatus, a channel in which the coolant is made to circulate by a pump is disposed to pass through the vicinity of a thermal fixing part and a paper feed cassette in which paper is stored. In the apparatus, when a power source is turned on, the warm-up of the fixing part is started (S1), and the pump is turned on (S3). Thus, the coolant circulates, and the heat exchange that the heat is applied to the paper while receiving the heat from the fixing part is performed during the circulation of the coolant. A paper ambient temperature T1 is detected (S4). When T1 is lower than a predetermined value α (S5"N"), it is determined that a paper temperature is lowered to such an extent that it influences the image quality, whereby printing is inhibited (S6). When the paper temperature rises and T1 becomes not lower than α (S5"Y"), the inhibition of printing is canceled (S9), and when the warm-up is finished (S10"Y"), the apparatus is shifted to a ready state in which printing can be performed (S11).
