PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of determining an in-device temperature at a proper timing, and effectively performing control to suppress an increase in the in-device temperature.SOLUTION: When an atmospheric temperature U around a printer 200 is included within a predetermined atmospheric low-temperature range (U≤Uth), the printer 200 sets a long determination cycle Qlong to a temperature determination cycle Q. Alternatively, when the atmospheric temperature U is included within a predetermined atmospheric high-temperature range (Uth<U), the printer 200 sets a short determination cycle Qshort to the temperature determination cycle Q. The printer 200 determines an in-device temperature T of a developing unit 7 in a cyclic manner with the set temperature determination cycle Q. |
