Abstract
An image forming apparatus having a fixing apparatus for nipping a recording material bearing an unfixed toner image on the surface thereof by a nip portion between a fixing member and a pressure member and fixing the unfixed toner image on the surface of the recording material has a first temperature detecting element and a second temperature detecting element for detecting the temperatures of the fixing member and the pressure member, respectively, and electric power supplied to a heating portion for heating the fixing member is controlled in conformity with the detected temperature by the first temperature detecting element. When image forming on a plurality of recording materials is to be continuously effected, the conveyance interval of the recording materials is controlled so as to become short when the detected temperature of the pressure member is high, and to become long when the detected temperature of the pressure member is low.
