A fixing device may include first and second fixing members arranged to form a nip portion, an urging member that provides an urging force to urge the first fixing member toward the second fixing member, a change member configured to change a width of the nip portion from a first nip width to a second nip width by applying a pressing force to the first fixing member against the urging force of the urging member and change the width of the nip portion from the second nip width to the first nip width by releasing the pressing force, and a restriction portion configured to restrict movement of the first fixing member and restrict a maximum value of the first nip width of the nip portion while the pressing force against the urging force is released. |
