A fixing apparatus capable of performing, even by a short brake, brake assist by which a sheet is stopped at a position where the sheet is visible. Upon occurrence of a wrap jam, brake control for a drive motor and brake assist control are performed. In the brake assist control, a pressing process is performed based on the number of assist operation pulses, which is set in advance. When an edge of a home position sensor signal is detected, a process for stopping the pressing process is carried out, whereby a pressing unit assumes a maximum pressing position.
