Abstract
Roll fuser apparatus for fixing toner images to copy sheets by the application of heat and pressure. The apparatus is characterized by the provision of a backup roll which can be quickly removed from the apparatus with a minimum of handling. To this end the backup roll is supported in the apparatus by a pair of frame members which are bolted to a backup roll support member which forms an integral part of the apparatus. A pair of hook-like members support the backup roll after the bolts have been removed; therefore, the backup roll need not be handled prior to the removal of the bolts and then it can be simply lifted out of the apparatus. Replacement is likewise simple.
