Abstract:
1. An optical scanning device comprising: a light source that emits a light beam; a deflector that deflects the light beam from the light source; a first optical system that guides the light beam from the light source to the deflector; a second optical system that guides the light beam from the deflector to a surface to be scanned; and a housing that holds the light source and the deflector, wherein at least one optical element included in one of the first optical system and the second optical system is attached to the housing via at least one intermediate member, the optical element configured to be eccentrically adjusted about an axis parallel to at least a sub-scanning direction, wherein the optical element is configured to be adjusted in two or more directions with respect to the at least one intermediate member, wherein the at least one intermediate member includes a surface which abuts the optical element and is fixed to the optical element by adhesion, and wherein the at least one intermediate member further includes a surface which abuts the housing and is fixed to the housing by adhesion, and wherein the at least one intermediate member is configured to be adjusted in two or more directions with respect to the housing.
