ABSTRACT:
A fixing device for fixing images of an original document on a copy material is provided for a plain paper copier. The fixing device comprises a pair of rollers for stressing under pressure the copy material carrying toner powder thereon. The toner powder is tightly adhered to the surface of the copy material to correspond to the images of the original document. In a preferred form, the toner powder is a pressure-fixable developing powder which consists of a wax component and a thermoplastic resin. A developing powder supplier is disposed within a developer powder reservoir for supplying developer powder to a magnet brush. A rotatable cylindrical magnet is provided within said developing powder supplier for generating a non-uniform magnetic field to stir the developer powder within the reservoir. A copy sheet stripping device is also provided which moves in synchronization with the approach of a copy sheet towards the fixing device and to move in synchronization with the separation of the copy sheet away from the fixing device.
