Abstract: An exposure device capable of precisely focusing light on a scanned surface to accomplish a good image quality is provided. The exposure device includes a substrate on which a plurality of light sources are arranged along a main-scanning direction, a lens array including a plurality of lenses configured to focus light emitted by the plurality of light sources on a scanned surface, and a housing configured to support the substrate and the lens array such that a certain spacing is maintained between the plurality of light sources and the plurality of lenses. At least a portion of the substrate is spaced apart from the housing along a sub-scanning direction.

Abstract: A light scanning unit and an electrophotographic image forming apparatus are provided. The light scanning unit includes a light source unit for emitting a light beam, a light deflector for scanning and deflecting the light beam, an imaging optical system having an imaging lens for imaging the scanned and deflected light beam, and first and second reflection members arranged on an optical path, a housing, and first and second assembly members for pressing and fixing the first and second reflection members on the housing. The assembly members press and fix the reflection members on the housing by pressing the reflection members in a direction in which curvature of a scanning line due to the inclination of the first reflection member and curvature of a scanning line due to the inclination of the second reflection member are offset with each other.
