Abstract
Corrected power for compensating for a reduction in the temperature of an endless belt that accompanies the entry of a recording material into a fixing nip portion is adjusted by correcting the power supplied to a fixing unit when the recording material enters the fixing unit with a correction power based on the difference between the update time of a power updating period and the time of the entry of the recording material.
