<P>PROBLEM TO BE SOLVED: To provide an optical scanner capable of cost reduction and miniaturization. <P>SOLUTION: A scanning optical system B includes: a scanning lens 15B; a luminous flux LBc through the scanning lens 15B; a polarized light separating member 16B for separating the luminous flux LBc from a luminous flux LBd and a luminous flux LBe; a wavelength separation element 16C for separating the luminous flux LBd from the luminous flux LBd and the luminous flux LBe transmitted through the polarized light separating member 16B; folding mirrors (17c, 18c) for guiding the luminous flux LBc separated by the polarized light separating member 16B to a photoreceptor drum 2030c; folding mirrors (17d, 18d) for guiding the luminous flux LBd separated by the wavelength separation element 16C to a photoreceptor drum 2030d; a folding mirror 17e for guiding the luminous flux LBe transmitted through the wavelength separation element 16C to a photoreceptor drum 2030e. <P>COPYRIGHT: (C)2013,JPO&INPIT |
