摘要
<P>PROBLEM TO BE SOLVED: To provide a lens array for suppressing deterioration in resolution. <P>SOLUTION: A lens array used in an image forming apparatus and a scanning device is so formed that outer lens surfaces 13A and 13B are formed to be inclined to inner lens surfaces 14A and 14B by a predetermined inclination angle TX, and the outer lens surfaces 13A and 13B are eccentrically formed by an eccentric distance EX in a direction of crossing an optical axis ALX of the inner lens surfaces 14A and 14B with an optical axis AXO of the outer lens surfaces 13A and 13B in the outer lens surfaces 13A and 13B side. The eccentric distance EX is a distance where a distance of displacement of imaging position due to inclination of the outer lens surfaces 13A and 13B substantially matches a distance of displacement of imaging position due to eccentricity of the outer lens surfaces 13A and 13B. <P>COPYRIGHT: (C)2013,JPO&INPIT
