The reflected light is projected into the image carrier by way of the fourth reflecting mirror at which the light transmitted by the fixed-focus lens is reflected. The lens unit accommodates the fixed-focus lens and is movable in the same moving direction as the first, second and third reflecting mirrors at the time of an image magnification change operation. A lens cam member is mounted on the lens unit.
