Abstract
A fixing device includes an endless belt, a rotating member, a pad disposed inside the belt so as to nip the belt between itself and the rotating member and form a nip, and a sliding member disposed between the pad and the belt. The pad includes a curved portion which is curved so as to directly contact the belt in a downstream side of the nip in a conveyance direction of the recording material. The curved portion includes a first portion positioned in a downstream side, in the conveyance direction, of a passing through region where a recording material with a maximum size passes through the nip and a second portion positioned in a downstream side of a non-passing through region outside of the passing through region in a widthwise direction. A radius of curvature of the second portion is larger than a radius of curvature of the first portion.
