ABSTRACT:
An apparatus for fixing a copy paper for use in electrophotographic appliances, such as laser beam printers or copying machines, includes components for stretching the leading edges of copy sheets at the entry of the nip defined by the fixing station for preventing crumpling of the copy sheets, reverse pressure component for bowing downward and flattening the leading edges of the copy sheets, and cleaning device including a cleaning box provided with a roller brush which is rotatable in the same direction as the heating roller for cleaning up the periphery of the heating roller, and a brush cleaning member for dusting off the roller brush. With this arrangement, when two-sided copying of the copy sheets is performed, jamming of copying sheets is prevented, thus improving copying efficiency.
