Abstract
A light scanning unit includes: a light source generating and irradiating at least one beam corresponding to an image signal; a beam deflector deflecting and scanning the beam irradiated by the light source; and an f-θ lens forming an image from the beam deflected by the beam deflector onto a surface to be scanned, the f-θ lens being provided as one lens and satisfies the following equation (2): where SAGis Z value of an incident surface of the f-θ lens, which faces the beam deflector, SAGis Z value of the exit surface of the f-θ lens, which faces the surface to be scanned, based on an XYZ coordinate system in which a main scanning plane is a Y-Z plane and a sub-scanning plane is an X-Z plane, and dis a center thickness of the f-θ lens.
