Light scanning apparatus and image forming apparatus including the same

An apparatus, comprising:

• a deflecting unit including a first deflecting surface configured to deflect first and second light fluxes from first and second light sources to scan first and second surfaces in a main scanning direction, respectively;
• and
• first and second light guiding units configured to guide the first and second light fluxes from the first and second light sources to the first deflecting surface, respectively,
• wherein an optical path of the first light flux in the first light guiding unit includes a straight line connecting the first light source and the first deflecting surface, and
• wherein a first straight line passing through centers of light emitting surfaces of the first and second light sources is not parallel to a sub-scanning direction.

An apparatus, comprising:

• first and second deflecting units including first and second deflecting surfaces configured to deflect first and second light fluxes from first and second light sources to scan first and second surfaces in a main scanning direction, respectively;
• and
• first and second light guiding units configured to guide the first and second light fluxes from the first and second light sources to the first and second deflecting surfaces, respectively,
• wherein first and second on-axis deflection points on the first and second deflecting surfaces are on a plane parallel to a sub-scanning direction,
• wherein an optical path of the first light flux in the first light guiding unit includes a straight line connecting the first light source and the first deflecting surface, and
• wherein an optical path of the second light flux in the second light guiding unit does not include a straight line connecting the second light source and the second deflecting surface.
