<P>PROBLEM TO BE SOLVED: To provide an image forming device capable of suppressing a deflection, a displacement, etc. of an optical member. <P>SOLUTION: As its main components, a spring member 90 includes a first plate-like portion 91; a second plate-like portion 93 disposed at a predetermined angle with the first plate-like portion 91, and arranged facing the first plate-like portion 91; and a curved portion 92 formed curved in a U-shaped manner, and its cross section is V-shaped as a whole. The first plate-like portion 91 has a domy protrusion part 91b on its face on the side opposite to the side where the second plate-like portion 93 is disposed. The first plate-like portion 91 has a stopper portion 91a at its edge on the side opposite to its edge to which the curved portion 92 is joined, bent in the direction away from the second plate-like portion 93, and disposed facing the edge face in the longitudinal direction of the loopback mirror. The first plate-like portion 91 also has a first protrusion strip 91c formed protruding in the width direction of the spring member 90. <P>COPYRIGHT: (C)2009,JPO&INPIT |
