A fixing device has a first roller, a second roller, a peeling member
located on a sheet exit side relative to the paired rollers to be guided
in a direction away from the first roller, and a positioning mechanism
configured to position the peeling member. The positioning mechanism has a
support shaft located on the sheet exit side relative to the first roller
in a state parallel to the axis of the first roller, a positioning member
carrying the peeling member, supported by the support shaft to rotate
toward and away from a roller shaft, and configured to abut a peripheral
surface of the roller shaft, and an elastic member configured to urge the
positioning member in a direction to abut on the peripheral surface
portion of the roller shaft.
