Light scanning apparatus and image forming apparatus

A light scanning apparatus, comprising:

• a deflecting unit including first and second deflecting surfaces configured to deflect first and second light fluxes to scan first and second scanned surfaces in a main scanning direction;
• and
• first and second imaging optical systems configured to condense the first and second light fluxes deflected by the deflecting unit on the first and second scanned surfaces, wherein
• the first imaging optical system includes one or more imaging optical elements and a first reflective element arranged on an optical path between a first imaging optical element and the deflecting unit, the first imaging optical element having the greatest refractive power in a sub-scanning section out of the one or more imaging optical elements,
• the second imaging optical system includes one or more imaging optical elements and a second reflective element arranged on an optical path between a second imaging optical element and the second scanned surface, the second imaging optical element having the greatest refractive power in the sub-scanning section out of the one or more imaging optical elements,
• a straight line, which passes through first and second light-condensing positions of the first and second light fluxes deflected by the deflecting unit on first and second optical axes of the first and second imaging optical systems, is not perpendicular to a sub-scanning direction, and
• the following conditional expression is satisfied:
• L1/T1>L2/T2,
• where L1 represents a distance on the first optical axis between a first axial deflecting point on the first deflecting surface and the first imaging optical element, T1 represents a distance on the first optical axis between the first axial deflecting point and the first scanned surface, L2 represents a distance on the second optical axis between a second axial deflecting point on the second deflecting surface and the second imaging optical element, and T2 represents a distance on the second optical axis between the second axial deflecting point and the second scanned surface.
