Abstract

An optical scanning device includes a scanning optical system, a housing, a skew adjustment mechanism, and a control unit. The skew adjustment mechanism rotates a skew adjustment motor in a fixed direction, so as to periodically change position of an optical element. When rotating the skew adjustment motor by a rotation amount corresponding to a half period of position change of the optical element, average value of the position change of the optical element is substantially the same as average value of the position change of the optical element per one period. The control unit calculates rotation amount of the skew adjustment motor necessary for returning the optical element to the reference position, on the basis of rotation amounts of the skew adjustment motor at three points obtained by equally dividing the position change of the optical element per half period into two, and skew amounts.
