Abstract
An image heating apparatus includes a heating rotary member, which heats an image on a recording material at a nip portion, an air blowing device for blowing air toward an air blowing port to cool a predetermined area of the heating rotary member, a shutter, which opens and closes the air blowing port, and a determination device. The determination device determines an execution of an operation of the air blowing device with the shutter opened after a first job is completed, in accordance with a size of a recording material in a width direction perpendicular to a recording material transport direction in a second job for supplying a recording material, between an execution termination of the first job for continuously supplying recording materials having a size smaller than a predetermined size in the width direction, while operating the air blowing device, and a start of a recording material supply of the second job, in a case that the second job is executed subsequent to the termination of the first job.
