Abstract
A laser light scanning apparatus includes: an optical system that generates parallel light from laser light emitted from a light source; an optical deflector that performs one-dimensional deflection on the parallel light from the optical system; and a diffractive optical element that diffracts deflected light from the optical deflector. The diffractive optical element is configured such that the diffracted light is focused along a predetermined axis that extends from the optical deflector toward the diffractive optical element, and the position at which the diffracted light is focused on the predetermined axis changes according to the incidence position of the deflected light.
