ABSTRACT:
A fixing apparatus operates to fix a toner image on a recording medium. A heating member extends in a first direction transverse to a second direction in which a recording medium travels for fixing. A belt contacts the heater member to form a fixing region between the belt and the heating member. A pressure member presses the belt against the heating member. A pressing mechanism engages the pressure member to apply a predetermined pressure to the pressure member toward the fixing region in such a way that the pressure has a predetermined profile of distribution in the first direction. The pressing mechanism may be a rotatable member. When the rotatable member rotates, the surface of the rotatable member moves into pressure contact engagement with the pressure member.
