Abstract:
An image forming apparatus includes: a photoconductor; an exposure portion that exposes the photoconductor; a fan that generates an airflow for cooling the exposure portion; a duct portion that communicates with the fan; and an elevating duct that relatively moves with respect to the duct portion integrally with the exposure portion, in which the elevating duct includes a rib protruding in a direction away from the exposure portion in a vertical direction, the duct portion includes a sealing member surrounding an opening portion that communicates with the elevating duct, when the elevating duct is located at an exposure position, a surface of the rib intersecting a rotation axis of the photoconductor is in contact with the sealing member, and when the elevating duct is located at a retracted position, a surface of the rib intersecting with the rotation axis of the photoconductor is in contact with the sealing member.
