Abstract:
An optical scanning device includes light sources, a deflector deflecting light beams emitted from the light sources, a first lens transmitting the light beams deflected by the defector, and second lenses guiding the light beams transmitted from the first lens to respective surfaces to be scanned. The second lenses are arranged so that a first incident position of a first light beam emitted by a first light source and entering one of the second lenses is closer to the respective surface to be scanned along an optical axis of the first lens than a second incident position of a second light beam emitted by a second light source and entering another of the second lenses, and an incident angle of the second light beam with respect to the optical axis along a deflection direction by the deflector is greater than the incident angle of the first light beam.

Claim (Index 11):
An image forming apparatus comprising:\n a plurality of image carriers having respective surfaces to be scanned; an optical scanning device that comprises: a plurality of light sources each corresponding to the image carrier; a deflector configured to deflect light beams emitted from the plurality of light sources; a first lens configured to transmit the light beams deflected by the defector; and a plurality of second lenses configured to guide the light beams transmitted from the first lens to the respective surfaces to be scanned, wherein\n the second lenses are arranged so that a first incident position of a first light beam emitted by a first light source and entering one of the second lenses is closer to the respective surface to be scanned along an optical axis of the first lens than a second incident position of a second light beam emitted by a second light source and entering another of the second lenses, and \n an incident angle of the second light beam with respect to the optical axis along a deflection direction by the deflector is greater than the incident angle of the first light beam; and \n an image forming unit configured to form an image on an image receiving medium using a latent image formed on the respective surface to be scanned.
