ABSTRACT:
In an image fixing apparatus, a fixing roll unit is arranged in a predetermined path along which a continuous form travels, for applying pressure and/or heat to an image on the continuous form to fix the image thereonto. An endless belt member is arranged upstream of the fixing roll unit with reference to a transport direction in which the continuous form travels along the predetermined path. The endless belt member has provided thereon a plurality of projections arranged in spaced relation to each other along an outer periphery of the endless belt member. The projections are engageable with sprocket holes formed in the continuous form along opposite side edges thereof. The endless belt member is capable of running in the transport direction while applying a predetermined back-tension to the continuous form traveling toward the fixing roll unit along the predetermined path.
