Abstract
In a fixing apparatus using a fixing belt having an elastic layer as a fixing member and an image forming apparatus mounting such a fixing apparatus thereto, before a temperature detecting unit detects temperature change caused upon recording material conveying into a nip region, an electric power required to be applied to a heating element to heat the heating element is corrected to a predetermined electric power, and, when the fixing apparatus is started-up upon starting of print, at a predetermined timing, the electric power required to be applied to the heating element to heat the heating element is corrected to the predetermined electric power and a value of the predetermined electric power is substantially the same as an electric power value required for reaching the fixing apparatus to the predetermined power. The value of the predetermined power is determined in accordance with heat capacity of the recording material or a heat accumulating degree of the fixing apparatus on demand.
