Abstract

A scanning optical device includes a deflector, a reflecting mirror, a housing to accommodate the deflector and the mirror; and an elastic member to urge the mirror toward the housing. The mirror includes a first surface urged by the elastic member, a second surface opposite to the first surface, a third surface and a fourth surface perpendicular to the first and second surfaces. The housing includes a bearing surface to support the second surface and a regulating portion to regulate movement of the mirror to a mirror widthwise direction, perpendicular to a mirror longitudinal direction and parallel with the second surface, and toward an opening of the housing. The regulating portion is provided opposite to only a part of the third surface so that a ridge line of the mirror between the second surface and the third surface does not contact the regulating member even an attitude of the mirror changes in a direction away from the bearing surface.
