Image heating apparatus

An image heating apparatus for heating an image on a recording material, comprising:

• a fixing member including a heating portion and configured to fix a toner image on the recording material in contact with the toner image formed on the recording material;
• a pressing member configured to form a nip in cooperation with said fixing member;
• a fan configured to cool said pressing member;
• and
• a controller configured to control an operation of said fan, wherein a temperature of said pressing member when the image is formed on a recording material having a first basis weight is lower than a temperature of said pressing member when the image is formed on a recording material having a second basis weight larger than the first basis weight,
• wherein when a mixed job including a first image forming step for continuously forming images on recording materials having the second basis weight and including a second image forming step, subsequent to the first image forming step, for continuously forming the images on recording materials having the first basis weight is executed, said controller switches, before a final recording material in the first image forming step completely passes through the nip, the operation of said fan to an operation of said fan for making the temperature of said pressing member lower than the temperature of said pressing member when the images are formed on the recording materials having the second basis weight.

• wherein when during execution of a first image forming job for continuously forming images on recording materials having the second basis weight, a second image forming job, executed subsequently to the first image forming job, for continuously forming the images on recording materials having the first basis weight is received, on the basis of a temperature of said pressing member when the second image forming job is received, said controller selects, before a final recording material in the first image forming step completely passes through the nip, whether or not an operation of said fan for making the temperature of said pressing member lower than the temperature of said pressing member when the images are formed on the recording materials having the second basis weight should be executed.
