<p>PROBLEM TO BE SOLVED: To determine the temperature of a fixing unit that starts image formation according to an external power source voltage value to reduce a power to be used for fixation.SOLUTION: In an image forming apparatus 1, an arithmetic processing part 71 matches, on the basis of a voltage value of an external power supply power PS, the timing of increasing a temperature to the fixing temperature at which images can be fixed to a fixing part 30 after the start of energization to a fixing heater 30c, with the timing at which a sheet having a toner image formed thereon reaches the fixing part 30, and determines a temperature of a fixing roller 30a of the fixing part 30 for a printer part to start image formation as the image formation start time; when the temperature of the fixing roller 30a detected by a thermistor 30d reaches the image formation start temperature, the arithmetic processing part 71 causes the printer part 40 to start image formation.</p> |
