Abstract
A fixing apparatus according to an embodiment includes: a first roller; a second roller that forms a nip between the second roller and the first roller and pressurizes a sheet passing through the nip against the first roller; a third roller that is disposed in parallel with the first and second rollers; a fixing belt that is stretched over the first and third rollers; a heater that uniformly heats the fixing belt in a direction of a width of the fixing belt; and a heat-uniformizing member that is a shaft-shaped heat-uniformizing member embedded in the third roller. An effective length in a longitudinal axial direction of the heat-uniformizing member is set to be the same or greater than a width of a predetermined maximum sheet so as to uniformly distribute heat of the fixing belt which is in contact with the third roller in the longitudinal axial direction.
