Patent ID: 7130553

Claim:
An image forming apparatus having a fixing apparatus for nipping a recording material bearing an unfixed toner image on a 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, comprising: a heating member provided in the fixing member and for heating the fixing member; a first temperature detecting element for detecting a temperature of said fixing member; an electric power controller for controlling electric power supplied to said heating member in conformity with the temperature of said fixing member detected by said first temperature detecting element; and an interval controller for controlling a conveyance interval of the recording materials when image forming on a plurality of recording materials is to be continuously effected, wherein although no heating member is provided in said pressure member, a second temperature detecting element for detecting a temperature of said pressure member is provided, and the conveyance interval of the recording materials is variably controlled based on the detected temperature of said pressure member by said second temperature detecting element.
