    摘要: An image forming apparatus includes an image forming portion. The image forming apparatus further includes a fixing portion having a fixing nip portion that heats and fixes the unfixed image and an discharge roller that discharges the recording material. In the case where the recording material is a plain paper that is equal to or larger than a predetermined size, the discharge roller conveys the plain paper in a range from a front edge to a rear edge at a predetermined speed. In the case where the recording material is a plain paper smaller than the predetermined size, the discharge roller conveys the plain paper at a first speed until the rear edge passes through the fixing nip portion, and the discharge roller conveys the plain paper at a second speed higher than the first speed after the rear edge has passed through the fixing nip portion.

    摘要: 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.
