Abstract
A fixing device includes an endless belt configured to heat a recording material, a pressure member contacting an outer circumferential surface of the endless belt to form a nip portion, and a pad. A length of the endless belt is larger than a length of the pad in a width direction of the endless belt. The pad includes a first surface forming the nip portion, a second surface facing the first surface, and a third surface connecting the first surface and the second surface in the width direction and formed in a conveyance direction of the recording material. And the third surface has a curved shape in a cross section orthogonal to the conveyance direction of the recording material.
