Abstract
An scanning unit scanner includes a light source and a polygon mirror unit. A front-to-rear rib is disposed between the light source and the polygon mirror unit and near the polygon mirror unit. An input side opening having a slit shape is formed as a cutout in the top edge of the front-to-rear rib. When laser light from the light source passes through the input side opening, the input side opening restricts the width of the light in a main scanning direction.
