Abstract
A fixing device includes a fixing member, a pressing member, a heat source, a detecting part and a control part. The pressing member forms a pressing area with the fixing member. A sheet is conveyed through the pressing area. The heat source includes a main heating part heating a center portion of the fixing member in a sheet width direction perpendicular to a conveying direction of the sheet and a sub heating part heating both end portions of the fixing member in the sheet width direction. The detecting part detects a temperature of the end portion of the fixing member. The control part determines operation timings of the main heating part and the sub heating part based on the temperature detected by the detecting part such that the center portion and the both end portions of the fixing member are heated to a constant temperature.
