Abstract
An optical scanner includes: a light source; a light deflector configured to deflect a light beam from the light source in a main scanning direction; a scanning lens through which the light beam having been deflected by the light deflector passes; a beam detector configured to detect the light beam; a mirror disposed between the light deflector and the scanning lens in an optical axis direction of the scanning lens and configured to reflect the light beam having been deflected by the light deflector toward the beam detector; and a wall portion configured to cover one end face of the mirror that faces the scanning lens, wherein the surface of the wall portion facing the scanning lens is tilted with respect to a sub-scanning direction orthogonal to the main scanning direction.
