摘要： An optical scanner includes a light source, an optical coupler, an optical line image unit, a deflector, and an optical scanning unit. The optical scanning unit includes scanning lenses that guide the beams to a surface to be scanned. A surface on the deflector side of the scanning lens closest to a deflection reflecting surface has a negative power in a vertical scanning direction, and is a special toric surface in which a radius of curvature in a vertical scanning changes from an optical axis of the lens surface toward a periphery of the horizontal scanning direction. An F number of the beams toward the surface to be scanned of the scanning lens in the vertical scanning direction is larger in a peripheral part than in a central part in an effective scanning width.

摘要： A multi-beam optical scanning device is disclosed that includes a light source emitting a bundle of rays, a first optical system coupling the rays into diverging rays, a second optical system condensing the diverging rays into linear rays extending in the main scanning direction, a light deflector deflecting the linear rays, and a third optical system condensing the deflected rays onto a scanning surface. The second and third optical systems include resin imaging elements. At least one resin imaging element of the second optical system has a negative power in a sub scanning direction and a surface configuration that is arranged to effectively compensate for a change in field curvature caused by a temperature change in a support member of the first optical system or the resin imaging element of the third optical system. The second optical system as a whole has a positive power in the main scanning direction.

摘要： In an optical scanning device, a resin lens having a power that is an inverse (negative) power of a scanning lens is implemented in an optical system placed before a deflector so that a change in beam pitch caused by environmental temperature change can be prevented even when a resin lens is used as the scanning lens. To realize optical scanning using this device, a bundle of rays emitted from a plurality of light sources is coupled into a desired state by a coupling lens, after which the bundle of rays is incident on a resin lens. The surface of incidence of this resin lens has a spherical surface configuration with a negative power, and the exit surface of this resin lens has a cylindrical surface configuration with a negative power only in the sub scanning direction. Then, the bundle of rays passes through a resin lens that has a negative power only in the sub scanning direction and then enters a glass toroidal lens. A light deflector deflects the bundle of rays from the toroidal lens and the deflected bundle of rays is incident on a third optical system that compensates for a field curvature in each of the main scanning direction and the sub scanning direction, and focuses the bundle of rays onto a surface to be scanned while securing a desired beam pitch in the sub scanning direction.
