| titleOfInvention | Scanning optical system, optical scanning device, and image forming apparatus |
| abstract | In order to reduce the size of the apparatus and suppress the decrease in transmittance due to white turbidity, the scanning optical system performs main scanning by deflecting the light beam from the light source device 1 that emits a light beam having a wavelength of 500 nm or less and the light source device 1. It has a deflection optical system 5 that scans in the direction y, and a scanning imaging optical system 8 that forms an image of the light beam deflected by the deflection optical system 5 on the surface to be scanned H. The scanning imaging optical system 8 is provided adjacent to the deflection optical system 5 and includes a first lens 6 made of plastic having a predetermined alicyclic structure-containing resin as a base material. When the numerical aperture in the sub-scanning direction z of the incident light beam is NA1, and the distance between the deflection optical system 5 and the first lens 6 is t1 [mm], 0.05 ≦ NA1 · t1 ≦ 1.5 Meet. |
