Abstract
An optical scanning device includes two cleaning holders. The two cleaning holders each include two cleaning members. The two cleaning holders are connected to a wire-shaped member. In accompaniment of circulation of the wire-shaped member, the two cleaning holders travel to cause the cleaning members to slide on corresponding transmissive members. Upon one of the two cleaning holders coming into contact with a first stopper at one end of its travel path, a circulating direction of the wire-shaped member is reversed. Upon the other of the two cleaning holders coming into contact with a second stopper at one end of its travel path, the wire-shaped member stops circulating.
