力定着装置を提供することが可能である。[Effects of the Invention] For this reason, the present invention reliably fixes the supplementary 6 agent onto the recording paper by transferring the rotating fixing roll while pressing the recording paper against the recording paper with a pressure corresponding to the elastic force of the elastic member. Therefore, it is possible to provide a pressure fixing device that can be miniaturized and cost-effective.
