Abstract:
A fixing device includes a frame, a pressure arm pivotably supported on the frame, and a nip release lever supported on the pressure arm. The pressure arm can release pressure contact between a heating roller and a pressure roller. The nip release lever can move between a pressing position and a release position so as to move the pressure roller between a position at which the pressure roller applies pressure to the heating roller and a position at which the pressure roller applies no pressure. The nip release lever can be halted in the release position.
