Abstract
A duct for guiding air outside an image forming apparatus to a charging device includes: a first flow passage; a second flow passage bent from the first flow passage and extending in a direction orthogonal to a rotational direction and a rotational axis direction of a photosensitive drum, the second flow passage being provided with an outlet; and a plurality of flow dividing plates provided in the second flow passage, the plurality of flow dividing plates being disposed in parallel along the rotational axis direction and forming a third flow passage between the flow dividing plates adjacent to each other, in which a relationship between a length in the orthogonal direction and a length in the rotational axis direction of the third flow passage is a predetermined relationship.
