25. An optical scanning device comprising:
a frame;
an optical member holding device disposed in the frame and comprising;
a first supporting section supporting a first optical member;
a second supporting section supporting a second optical member positioned opposite to the first optical member;
a connecting portion connecting the first supporting section to the second supporting section; and
an adjustment section for adjusting a relative position between the first optical member and the second optical member, the adjustment section allowing the second supporting section to be movable and position fixable with respect to the first supporting section as if the second supporting section serves as a lever that bends about the connecting portion that functions as a fulcrum;
a rotatable polygonal mirror disposed in the frame and changing reflecting direction of a light flux emitted from the optical member holding device for scanning;
a drive unit disposed, in the frame and rotating the polygonal mirror; and
an image focusing unit disposed in the frame for focusing the scanned light flux onto an imaging medium.
