Abstract
A photosensitive drum has a drum sleeve and a pair of drum flanges. At least one of the pair of drum flanges each has a flange part, a retaining part, and a linking part. The flange part is fitted to the drum sleeve. The retaining part, which is located inward of the flange part in the axial direction of the drum sleeve, pivotably supports a shaft that rotates the photosensitive drum. Openings are formed between the flange part and the retaining part in a direction intersecting the axial direction. An air flow enters the interior of the photosensitive drum from the openings.
