Abstract
A fixing device, includes: a heating member that rotates in a state heated by a heating unit; a driven member that is rotated by the heating member, and that conveys a sheet in cooperation with the heating member; a biasing unit that biases the heating member and the driven member in a contacting direction; a contact area forming member that forms a contact area of the heating member and the driven member by making the heating member and the driven member come in contact with each other; a support member that supports at least one of the heating member and the driven member so as to be freely moved in a direction approaching and separated with respect to the other member; and a fulcrum that is arranged in a downstream side of the contact area in a sheet conveying direction, and that movably supports the support member.
