Abstract
An image forming apparatus comprises an image forming unit including a photosensitive drum (image bearing body) 11, and an exposure unit including an exposure head that emits light to expose the photosensitive drum to form a latent image. The exposure unit has a duct unit extending in the X direction (longitudinal direction) of the image forming unit. The duct unit has an inlet opening through which air flows into the duct unit and an outlet opening through which the air is discharged from the duct unit. The exposure unit is provided pivotably about a pivot axis (virtual straight line) passing through the inlet opening.

An image forming apparatus comprising:
- an image forming unit including an image bearing body;
- and
- an exposure unit including an exposure portion that emits light to expose the image bearing body to form a latent image,
- wherein the exposure unit has a duct unit extending in a longitudinal direction of the image forming unit,
- wherein the duct unit has an inlet opening through which air flows into the duct unit and an outlet opening through which the air is discharged from the duct unit, and
- wherein the exposure unit is provided pivotably about a virtual straight line passing through the inlet opening.
