<P>PROBLEM TO BE SOLVED: To provide an optical scanner in which the shift of a resist pattern is suppressed. <P>SOLUTION: The optical scanner 20 is used in an image forming apparatus in which a plurality of photoreceptor drums are provided in parallel. A housing 27 houses optical components and has a plurality of openings OY, OM, OC and OK through which a plurality of beams By, Bm, Bc and Bk which are deflected in a main scanning direction with the optical components are emitted. A positioning pin 51 determines the position of the housing 27 with respect to the image forming apparatus. The positioning pin 51 is arranged between the two adjacent openings OM and OC interposing the intermediate line of the two openings OY and OK in the direction perpendicular to the main scanning direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
