<P>PROBLEM TO BE SOLVED: To provide a positioning structure for fixing an optical element such as a lens at a predetermined position in an optical scanner that an image formation apparatus includes, a positioning structure that positions the optical element by providing a part where the optical element is positioned on a housing side of the optical scanner in a method of manufacturing the optical scanner, and then prevents or suppresses position shifting of the optical element due to environmental change, the method of manufacturing the optical scanner, the optical scanner obtained using those positioning structure and the method of manufacturing the optical scanner, and the image formation apparatus including the optical scanner. <P>SOLUTION: Separation members 86a, 87a are used which separate reference members 86, 87 from a support member 85 and releases the reference members 86, 87 and optical member 83 from abutting against each other while the optical member 83 occupies a predetermined position where the optical member 83 abuts against the reference members 86, 87 by applying external force to the reference members 86, 87 while the optical member 83 is located at the predetermined position. <P>COPYRIGHT: (C)2013,JPO&INPIT |
