FIXING DEVICE AND IMAGE FORMING APPARATUS

A fixing device includes a hollow rotating body that rotates about an axis of the rotating body, a pressing member that applies, together with the rotating body, pressure to a recording medium and transports the recording medium in a transport direction along with rotation of the rotating body, a heating member that is disposed in such a manner as to be in contact with an inner surface of the rotating body while extending in an axial direction perpendicular to the transport direction and that heats the rotating body, the heating member including a contact portion at least a portion of which is brought into contact with the inner surface and non-contact portions that are positioned on either side of the contact portion in the axial direction in such a manner as not to be in contact with the rotating body and each of which has a second end portion thicker than a first end portion of the contact portion on a downstream side in the transport direction, and a holding member that holds the heating member by being brought into contact with at least the second end portions in the transport direction.
