摘要： A scanning optical device that scans a photoreceptor with laser light includes a light source, a light outputting section, and a projection. The laser light from the light source is output through the light outputting section so that the photoreceptor is irradiated with the laser light. The projection projects through a partition wall toward the photoreceptor. The light outputting section is disposed in a position separated from the photoreceptor by the partition wall. The projection contains a polygon motor that rotates a polygon mirror to reflect the laser light.
