Abstract
An apparatus for installing a curved mirror used in a scanning optical system is provided. The apparatus his a curved mirror assembly that includes a wall and a reference surface which is formed on a surface of said wall. The apparatus also has a stationary member with which the scanning optical system is provided and to which the curved mirror assembly is secured. The curved mirror assembly is secured to the stationary member by using the reference surface without the reflecting surface coming in contact with the stationary member.
