<p>The fixing device includes first and second heat sources, a rotatable fixing member heated by the first heat source, a rotatable pressing member heated by the second heat source and contacting the fixing member to form a fixing nip therebetween at which a toner image on a sheet is fixed thereto, and at least first and second temperature detectors determining temperatures of different surface portions of the pressing member. The pressing member has a width greater than that of the fixing member greater than the maximum width of the sheet accommodated by the fixing device. The first temperature detector determines the temperature of a surface portion of the pressing member, which is to be contacted with the sheet, and the second temperature detector determines the temperature of a second surface portion of the pressing member, which is not contacted with the fixing member even when the pressing member is rotated.</p> |
