Abstract

A fusing apparatus 14 for fusing toner onto paper includes a heater roller 2 and a separating unit 15 with a separation claw 16. The separation claw 16 is provided with a paper guide member 17 having a curvature in a direction opposite to the curvature from a point a to a point c on the heater roller 2. After fusing, the front end 10a of the separated paper 10 is guided by the paper guide member 17. The paper guide member 17 reforms a curl imparted by the heating roller 2 curl into the original state, even if the paper 10 sticks to the heater roller 2 until the point c.
