Energy savings in an image forming apparatus

An image forming apparatus, comprising:

• a fixation member;
• a pressurization member that is pressure-contacted with the fixation member;
• a heat source that heats the fixation member;
• a drive unit configured to provide a drive force to the fixation member;
• a measurement unit configured to measure an elapsed time from powering off the heat source until receipt of an instruction to perform a next image forming processing;
• and
• according to receipt of the instruction to perform the next image forming processing, a control unit configured to cause the drive unit to start to drive the fixation member after a temperature of the fixation member reaches a first control temperature if the elapsed time does not exceed a predetermined threshold, and to cause the drive unit to start to drive the fixation member after the temperature of the fixation member reaches a second control temperature that is higher than the first control temperature if the elapsed time exceeds the predetermined threshold.
