The cylindrical lens of these two lenses is located between the rotating polygon mirror and the scanning lens for image-forming light in the subscanning direction, the scanning lens of these two lenses is located between the cylindrical lens and the image formation plane for image-forming light in the mainscanning direction. Also, magnification of the mainscanning direction and that of the subscanning direction are independent.
