ABSTRACT:
A light source part has a light source unit in which the plurality of light sources respectively emitting the light beams at angles different in a sub-scanning direction with respect to an optical standard plane, parallel to a main scanning direction and passing through a standard axis of a surface shape of a lens of the imaging part, which lens is closest to the deflecting part, and applied to the deflecting part at angles different in the sub-scanning direction, are integrally provided; and the plurality of light sources are inclined so that the plurality of light sources thus respectively emit the light beams at the angles different in the sub-scanning direction with respect to the optical standard plane.
