Abstract
An image forming apparatus forms a recorded image of an original image on a recording sheet by an electrophotography method. An optical scanning unit emits a laser beam which scans a surface of a photosensitive drum. The image forming apparatus is provided with a light absorbing member for absorbing the laser beam which is reflected by the surface of the photosensitive drum so as to prevent a flare from being generated.
