Abstract
A cylindrical lens for use in a light beam scanning optical system is arranged to have a luminous flux enter a deflection device in straight line in the direction of deflection. The luminous flux deflected by the deflection device enters a toroidal lens and is then directed toward the concave surface of the cylindrical mirror or a spherical mirror to converge on the surface of a photoconductor.
