Abstract:
An image heating apparatus includes a heater, a pressor, first and second temperature sensors, a controller, first and said coolers for cooling a surface of the heater and the pressor, respectively, a contact-spacing device for establishing a contact state of the heater and pressor and a spaced state of the heater and the pressor, a portion for executing first and second cooling modes in which at least one of the coolers is operated while rotating the heater and pressor in the contact state and in which the first and second coolers are operated while rotating the heater and pressor in the spaced state, respectively, and a selector for selecting the first cooling mode or the second cooling mode on the basis of an output of the second temperature sensor.
