Abstract

A fixing apparatus installed in a copying machine or the like and having a fixing roller, a pressure roller and sheet separator pawls engagable with the fixing roller. A first mechanism of the fixing apparatus is operable to locate free or separating ends of the sheet separator pawls at a small spacing from the periphery of the fixing roller. A pivotable second mechanism is operable to move the sheet separator pawls over a substantial distance away from the fixing and pressure rollers to define a large space in front thereof, so that the peripheries of the rollers become accessible for services.
