Abstract:
1. An image heating apparatus comprising: a heating rotatable member for heating a toner image on the recording material by a nip; a nip forming member for cooperating with said heating rotatable member to form the nip; a sensor for detecting jamming of the recording material in the nip; a first controller for interrupting an image heating operation of said heating rotatable member when said sensor detects the jamming of the recording material, and for resuming the image heating operation after the jamming is cleared; a rubbing member for rubbing a surface of said heating rotatable member; a moving mechanism for moving said rubbing member from a position for spacing said rubbing member from said heating rotatable member to a position for rubbing the surface of said heating rotatable member; and a second controller for executing an operation of moving said rubbing member to the rubbing position to rub the surface of said heating rotatable member when a predetermined condition is reached, wherein, when the sensor detects jamming of the recording material in the nip, said second controller delays moving said rubbing member by a predetermined count of recording materials passing the nip after the jamming is cleared.
