Abstract

A fixing unit has a fixing roller and an endless belt. When a recording sheet bearing a toner image not yet fixed passes between the fixing roller and the endless belt, the fixing unit fixes the toner image onto the recording sheet in the nip area. The endless belt is a film-like belt consisting of a base film and a layer on the base film, the layer being made of a composite material containing porous material and elastomer. A fixing unit is thus provided which is free from the problems of image offset and lifetime shortening, and can realize the increase of fixing speed and/or size reduction.
