Abstract
A fixing device for fixing a developing agent image on a recording medium includes a heat roller and a compression roller for pressing the recording medium against the circumferential surface of the heat roller. A discharge guide for guiding the recording paper passing between the rollers, away from the heat roller is arranged near the heat roller. The discharge guide has an end portion located adjacent to the heat roller, and is positioned by a positioning mechanism so that a predetermined distance is defined between the end portion of the discharge guide and the heat roller. The end portion of the guide is spaced away from the heat roller by spacers made of a relatively soft material. A cleaning element is positioned between the spacers. The spacers and cleaning element are biased against the heat roller by a spring force.
