Image-forming apparatus including link connected to shutter of fixing device and positioned between fan and circuit board

An image-forming apparatus comprising:

• a housing to which a cartridge is detachably attachable;
• a fixing device configured to thermally fix a toner image to a sheet conveyed in a sheet conveying direction, the fixing device comprising a heating unit including a heater, the heating unit having an upstream end in the sheet conveying direction;
• a shutter movable relative to the fixing device between a closing position where the shutter covers the upstream end of the heating unit and an opening position where the shutter uncovers the upstream end of the heating unit;
• a link connected to the shutter, the link being configured to abut on the cartridge to move the shutter between the closing position and the opening position;
• a circuit board on which an electronic component is mounted;
• and
• a fan configured to move air in the housing,
• wherein
• the circuit board and the fan are spaced apart from each other to provide an airflow path through which the air flows, and
• the link is positioned between the circuit board and the fan.
