an apparatus main body to which a cartridge is detachably attachable;
a fuser including a heating rotor and a pressure rotor configured to form a nip therebetween;
a shutter movable between a closed position at which the shutter covers the nip and an open position at which the nip is exposed; and
a link configured to contact the cartridge, the link being coupled to the shutter and configured to move the shutter between the open position and the closed position, the link being movable between a first position at which the cartridge is not attached to the apparatus main body and a second position at which the cartridge is attached to the apparatus main body,
the link and the shutter being configured that:
when the cartridge being attached to the apparatus main body contacts the link, the shutter moves from the closed position toward the open position;
before the shutter reaches the open position, the link and the cartridge separate from each other; and
the link having separated from the cartridge moves further in a direction in which the shutter becomes the open position.
