Claim Text:
1. A light scanning apparatus to be mounted to a mounting portion of an image forming apparatus through an opening portion of the image forming apparatus including a photosensitive member, the light scanning apparatus comprising: a light source configured to emit a light beam; a deflecting device configured to deflect the light beam emitted from the light source so as to scan the photosensitive member with the light beam; an optical box including an outer wall and an inner wall extending inside the outer wall and along the outer wall so as to face the outer wall, and configured to hold the light source and contain the deflecting device inside the inner wall; and electric wires electrically connected to the deflecting device, wherein the optical box includes a space in which the electric wires are laid being formed between the outer all and the inner wall, wherein the electric wires cross over the inner wall, from a space on an inner side of the inner wall so as to be laid in the space formed between the outer wall and the inner wall, and cross over the outer wall from the space formed between the outer wall and the inner wall so as to lead to a space on an outer side of the optical box, and wherein the electric wires are laid in the optical box so that, in a state in which the light scanning apparatus is mounted to the mounting portion of the image forming apparatus, a portion at which the electric wires cross over the outer wall are provided closer to the opening portion of the image forming apparatus than a portion at which the electric wires cross over the inner wall.
