Abstract
A light scanning apparatus, including: a light source configured to emit a light beam; a beam splitter configured to split the light beam into a first and a second light beams; a rotary polygon mirror configured to deflect the first light beam to scan a photosensitive member; a motor configured to rotate the rotary polygon mirror; a first lens configured to guide the first light beam to the photosensitive member; an optical sensor configured to receive the second light beam; a second lens configured to condense the second light beam on the optical sensor; and an optical box has a wall standing from a bottom surface between a region in which the rotary polygon mirror and the motor are disposed and a region in which the second lens is disposed, and a height of the wall from the bottom surface is higher than a height of the rotary polygon mirror.
