Abstract
Official abstract text for this publication.
A fixing apparatus for fixing a toner image formed on a recording material includes a rotatable member; a cleaning unit for cleaning the rotatable member, the cleaning unit including a cleaning fabric for cleaning the rotatable member, a feeding roller on which the cleaning fabric is wound, and a winding-up roller for winding up the cleaning fabric fed from the feeding roller; and a load applying mechanism for applying a retarding force against a winding-up operation of the winding-up roller such that when a frictional force between the rotatable member and the cleaning fabric which is in a standstill state and which is in contact with the rotatable member which is rotating exceeds the retarding force of the load applying mechanism, the winding-up roller rotates to wind up the cleaning fabric.
