Abstract
A fixing device includes a rotatable endless belt, a pressing roller and a fixing pad. The pressing roller contacts an outer peripheral surface of the belt and forms a nip portion in cooperation with the belt. A toner image is formed in the nip portion and fixed onto the recording material by application of heat and pressure. The fixing pad contacts an inner peripheral surface of the belt. The fixing pad includes a contact area in contact with the inner peripheral surface of the belt. The contact area includes a downstream end portion with respect to a conveyance direction of the recording material. The downstream end portion includes a central portion and both end portions with respect to a widthwise direction of the belt. The central portion locates downstream of the both end portions with respect to the conveyance direction.
