Abstract
A scanning optical device includes a light source device, a rotational polygon mirror, a rotor which rotates together with the rotational polygon mirror, a stator which rotates the rotor, wherein a substrate for holding the stator includes a first regulation portion arranged so as to overlap with a portion of the rotor in a rotational axis direction of the rotor, and in a case where the rotor is caused to move in the rotational axis direction, the first regulation portion comes into contact with the rotor, and a second regulation portion is arranged in a position in relation with the first regulation portion so as to maintain the first regulation portion in a position where the first regulation portion overlaps with the portion of the rotor in the rotational axis direction, so as to regulate deformation of the first regulation portion.
