Abstract
An image heating apparatus including first and second rotatable members, first and second cooling fans, an air blowing port, a shutter member, a shutter controller, and a fan controller. The first cooling fan is provided at a position opposing a first region which is a part of an end portion region of the first rotatable member on one end side. The second cooling fan is provided at a position opposing a second region which is part of the end portion region. The second region is adjacent to the first region with respect to the longitudinal direction. The shutter controller is configured to control a position of the shutter member depending on a width size of a recording material. The fan controller is configured to independently control an operation of the first cooling fan and an operation of the second cooling fan depending on the width size of the recording material.
