Fixing apparatus

Abstract

In dual-side image formation, in order to suppress a difference in gloss between images on both sides of a recording material, the invention provides a fixing apparatus including a fixing member for fixing an image on the recording material by heat; a heat supply member for supplying heat from the exterior of the fixing member; dual-side image forming means which forms images on both sides of the recording material, wherein, in a dual-side image forming operation, a first image forming operation for forming an image on a first side of the recording material and a second image forming operation for forming an image on a second side of the recording material are executed repeatedly; and heat supply control means which controls heat supplied to the fixing member, wherein a heat supplying condition of the heat supply member is changed according to the side of the recording material when an image is fixed thereon.
