A fixing device includes a rotatable body; a rotatable endless belt having inner and outer peripheral surfaces; a first presser portion within the inner peripheral surface and pressing the outer peripheral surface onto the rotatable body to form a first nip, through which a recording medium passes, between the endless belt and the rotatable body; and a second presser portion within the inner peripheral surface and pressing the outer peripheral surface onto the rotatable body to form a second nip through which the recording medium passes. The first nip decreases in length in a recording-medium transport direction from a central area toward opposite ends in an axial direction. The second nip increases in length in the transport direction from a central area toward opposite ends in the axial direction, and has an upstream edge, in the transport direction, whose central area protrudes upstream relative to the opposite ends. |
