Abstract
A fixing apparatus which prevents a generation of wrinkles in a print paper and rapidly recovers a temperature of a fixing belt. The fixing belt is engaged with a fixing roller and a heat roller generating heat. A pressing roller is pressed against the fixing roller via the fixing belt so that a fixing process area is formed between the fixing roller and the pressing roller. The print paper is passed through the fixing process area so that a toner provided on the print paper receives a heat from the fixing belt. The fixing roller includes a foamed material layer elastically deformable by the pressing roller. A heat conductive member may be provided to transmit a heat from the heat roller to a portion of the fixing belt remote from the heat roller.
