Abstract

If inclination correction of scanning line is performed while the incident position of the laser beam is not suitable, the shape of a spot of the laser beam which forms an image on a photosensitive drum may not be uniform depending on the scanning position of the laser beam. The housing is provided with a U-shaped groove to which the convex portion of a lens hold member that holds the lens is engaged. With the position of the convex portion adjusted, the convex portion is attached and secured in the U-shaped groove. Thus, the installation position of the lens to an optical path of the laser beam is adjusted, and the lens can be rotated and adjusted in order to correct an inclination or a bending of scanning line.
