Image heating apparatus and image forming apparatus having a controller that controls temperature of a rotatable member based on execution of a rubbing process

An image heating apparatus comprising:

• first and second rotatable members configured to form a nip for heating a toner image on a sheet;
• a rotatable rubbing member configured to rub an outer surface of said first rotatable member;
• and
• a contact-and-separation mechanism configured to move said rotatable rubbing member toward and away from said first rotatable member;
• and
• a controller configured to control a temperature of said first rotatable member, depending on a total time of contact of said rotatable rubbing member with said first rotatable member, when the rubbing process is executed.

An image forming apparatus comprising:

• an image forming portion configured to form a toner image on a sheet;
• first and second rotatable members configured to form a nip for heating the toner image on the sheet formed by said image forming portion;
• a heating portion configured to heat said first rotatable member so that a temperature of said first rotatable member is a target temperature;
• a rotatable rubbing member configured to rub an outer surface of said first rotatable member;
• and
• a contact-and-separation mechanism configured to move said rotatable rubbing member toward and away from said first rotatable member;
• a counting portion configured to count a number of times of image formation;
• an executing portion configured to execute a rubbing process by said rotatably rubbing member depending on an output of said counting portion;
• and
• a controller configured to control a target temperature, depending on a number of times of the rubbing process executed by said rotatable rubbing member, when the rubbing process is executed.
