ABSTRACT:
An image fixing device comprises a supporting platform for supporting thereon a recording sheet on which a provisional image is formed, one or more of rollers adapted to roll over the surface of the recording sheet in a direction substantially transversely of a paper feeding direction, and a resilient member for applying a downward force to the rollers to thereby apply pressure to the surface of said recording medium for fixing the provisional image under pressure. The rollers are connected to an arm rotating or swinging about a shaft extending vertically with respect to the platform. The swinging amplitude may be adjusted to become applicable to recording sheets of different width. The resilient member may be a coil spring coiled around the shaft in such manner as to apply a downward directing force to the rollers. Alternatively, the resilient member may be a shaft spring which comprises the rotating or swinging arm.
