Abstract
An image forming apparatus, having a housing, a photosensitive drum, an exposure head, and a positioning piece, is provided. The housing has a boss. The photosensitive drum is configured to be accommodated in the housing. The exposure head is configured to expose the photosensitive drum and is movable between an exposable position, at which the exposure head exposes the photosensitive drum, and a retracted position, at which the exposure head is separated farther from the photosensitive drum than the exposable position. The positioning piece is configured to locate the exposure head at a predetermined position in the housing. The positioning piece has a cylinder fitted around the boss and an arc surface extending concentrically with a circumferential surface of the cylinder. The arc surface is configured to contact the exposure head.
