ABSTRACT:
An optical writing device includes a polygon mirror configured to guide a light beam emitted from a light source. The polygon mirror is disposed in a case. The case includes a cover unit and a pressure unit configured to exert pressure on the cover unit. Pressure exerted by the pressure unit on the cover unit is greater than pressure exerted on another portion of the cover unit.
