SCANNING LINE ADJUSTER, OPTICAL SCANNER INCORPORATING THE SCANNING LINE ADJUSTER, AND IMAGE FORMING APPARATUS INCORPORATING THE OPTICAL SCANNER

摘要

A scanning line adjuster, which is incorporated in an optical scanner and an image forming apparatus, includes an optical element, an attitude changer, and an optical element positioner. The optical element is disposed on an optical path extending from a light source to a scanned target object. The optical element has a positioning portion. The attitude changer changes an attitude of the optical element. The optical element positioner contacts the positioning portion to position the optical element. The optical element positioner contacts the positioning portion of the optical element in a direction perpendicular to a moving direction of the positioning portion of the optical element when the attitude changer changes the attitude of the optical element. The optical element positioner includes a contact end to contact the positioning portion. The contact end is made of a different material from the other part of the optical element positioner.
