Abstract
The present disclosure provides a light scanning unit and an electronic image forming apparatus including the light scanning unit. The light scanning unit includes a light source, a first optical unit, an optical deflector, and a second optical unit. The light source includes at least two light-emitting points; the at least two light-emitting points are distributed along a straight line; and an angle between an extension direction of a distribution line thereof and a main scanning direction or a secondary scanning direction of the light scanning unit includes an acute angle, where the main scanning direction is perpendicular to the secondary scanning direction. The first optical unit is configured to collimate at least two light beams emitted from the light source along the main scanning direction and to focus the at least two light beams emitted from the light source along the secondary scanning direction.
