Patent ID: 7542692

Claim:
An image forming apparatus comprising: an image forming device that forms an image on a recording material in accordance with a set width of the recording material; an image heating member which heats the image on the recording material at a nip portion; a first detecting member which detects a temperature of a first region of the image heating member, the first region corresponding to an outside region of a contact region in a width direction, the contact region being contactable with a recording material having the set width; a cooling portion that cools the first region of the image heating member in accordance with the output of the first detecting member; a second detecting member which detects a temperature of a second region of said image heating member, the second region corresponding to an inside region of the contact region in the width direction; and a notification portion that notifies of an abnormality in accordance with an output of the first detecting member and an output of the second detecting member, wherein said notification portion that notifies that the set width of the recording material does not match an actual width in a case where the detected temperature of said first detecting member is a normal temperature and the detected temperature of said second detecting member is an abnormal temperature, and the notification portion notifies that the cooling portion is abnormal in a case where the detected temperature of said second detecting member is a normal temperature and the detected temperature of said first detecting member is an abnormal temperature.
