Image forming apparatus having plural dividing plates in a duct for guiding air

An image forming apparatus comprising:

• a duct configured to guide air taken in the duct;
• and
• a fan configured to generate an airflow for taking air outside the image forming apparatus into the duct,
• wherein the duct includes:
• a first duct part extending in a first direction,
• a second duct part extending in a second direction crossing the first direction, and
• a plurality of dividing plates disposed within the second duct part and configured to divide at least partially air flowing in the second duct part, the plurality of dividing plates at least including a first dividing plate, a second dividing plate, and a third dividing plate, each extending in the second direction, wherein the first dividing plate is disposed closer to an intake port of the first duct part than the second dividing plate and wherein the first dividing plate and the second dividing plate are disposed between the intake port of the first duct and the third dividing plate,
• wherein the second dividing plate includes:
• an overlapping part which overlaps with the first dividing plate when viewed from the first duct part along the first direction, and
• an extending part which extends beyond an edge of the first dividing plate when viewed from the first duct part along the first direction,
• wherein the third dividing plate includes:
• an overlapping part which overlaps with the second dividing plate when viewed from the first duct part along the first direction, and
• an extending part which extends beyond an edge of the second dividing plate when viewed from the first duct part along the first direction, and
• wherein a surface facing the first duct part of each of the first, second and third dividing plates extends straight throughout in the second direction.
