Abstract
A color image forming apparatus fixes a superimposed multi-color toner image, heat-fused at a heating section of an intermediate transfer belt, onto a recording material at a fixing nip section at which a pressing roller presses against the intermediate transfer belt. The fixing nip section is provided at the downstream end of the heating section in a turning direction of the intermediate transfer belt. The present apparatus can accelerate a fixing rate while maintaining stable fixing properties for a multi-layer toner image of a color image having different layer thicknesses with any kind of recording papers under any operation condition, and requires a shorter warm-up period while attaining excellent heat efficiency.
