An optical scanning apparatus comprises a light source provided with a plurality of light emitting portions different in emission wavelength on a single stem, a deflector for deflecting a plurality of beams from the light source an optical system for converging the plurality of beams deflected by the deflector, and a wavelength separation device for separating the plurality of beams from the optical system from each other. The optical scanning apparatus may be applicable to a laser beam printer by combining it with a photosensitive member to which the plurality of beams separated by the wavelength separation device are guided.
