An image forming apparatus includes a rotatable image heating member for heating a toner image on a recording material in a nip; a rotatable pressing member for pressing against the image heating member to form the nip; a moving mechanism for relative movement between the heating member and the pressing member toward and away from each other; a temperature detecting member for detecting a temperature of the pressing member; cooling means for cooling the pressing member; rotational speed changing means for changing a rotational speed of the pressing member; and an executing portion for executing, when the temperature of the pressing member reaches an upper limit temperature during execution of an image formation job of continuously forming the images, a cooling mode for cooling the pressing member by the cooling means in a state that the pressing member and the heating member are spaced from each other while rotating the pressing member at a second rotational speed higher than a first rotational speed which is a speed during the execution of the job.
