An optical scanning device includes a plurality of converging lenses and a plurality of supporting members. Each supporting member supports a corresponding one of the converging lenses. Moreover, the converging lenses are arranged so as to be out of alignment with one another in a main-scanning direction and are arranged in a row in a sub-scanning direction in such a manner that no converging lens interferes with supporting members that support other converging lenses.
