Abstract:
1. A fixing device comprising: a heating rotatable body that is heated; a rotatable endless belt having an inner peripheral surface and an outer peripheral surface that is disposed facing the heating rotatable body; and a presser component having a first presser portion, a second presser portion, and a recess, the first presser portion being provided within the inner peripheral surface of the endless belt and pressing the outer peripheral surface of the endless belt onto the heating rotatable body in an opposed area where the endless belt and the heating rotatable body are opposed to each other so as to form a fixation nip between the endless belt and the heating rotatable body and through which a recording medium bearing an image passes, the second presser portion guiding the recording medium by pressing the endless belt toward the heating rotatable body at an upstream side of the fixation nip in a transport direction of the recording medium so as to bring the recording medium into contact with the heating rotatable body at the upstream side of the fixation nip in the transport direction of the recording medium, the recess being spaced apart from the endless belt and located upstream of the first presser portion in the transport direction of the recording medium and downstream of the second presser portion in the transport direction of the recording medium, wherein the second presser portion comprises a convex-curved shape that gradually bulges toward the heating rotatable body in a radial direction from opposite ends to a central area of the presser component in a width direction, wherein the first presser portion, the second presser portion and the recess are made by the same material, and wherein the first presser portion, the second presser portion and the recess are integrally formed.
