Abstract
In an image-forming apparatus, a shield case housing an optical fiber tube for projecting images on the surface of a photoconductive drum is movable to an exposure position close to the surface and to a non-exposure position away from the surface. A cleaning device cleans only the face of the optical fiber tube in the non-exposure position in response to the closing of the main switch of the apparatus and upon detecting that the tube is in the non-exposure position away from the surface of the drum.
