Abstract
An optical scanning device comprises two transmission optical components each having approximately planar surfaces on both sides thereof. These transmission optical components are disposed so as to have at least one scanning and imaging component inserted therebetween. The first transmission optical component is disposed at a light exit of a cover covering a light deflector. The second transmission optical component is disposed at a light exit of the optical housing. The two transmission optical components are inclined in a sub-scanning section included in a same direction in a straight line perpendicular to the surface to be scanned. The first transmission optical component is inclined with respect to the surface to be scanned in a deflection scanning plane. The second transmission optical component lies approximately in parallel to the surface to be scanned in the deflection scanning plane. The polarization directions of the beam directed to the light deflector are approximately perpendicular to the deflection scanning directions.
