Patent ID: 7088484

Claim:
An optical scanning apparatus, comprising: a light source having multiple light emission points and configured to emit a plurality of laser beams; a first optical mechanism including an optical element fixed to an integrated member that fixes the light source, and is configured to convert the plurality of laser beams emitted by the multiple light emission points of the light source into converging laser beams; a light deflective reflection mechanism configured to reflect and to deflect the plurality of laser beams; a scanning optical mechanism configured to lead the plurality of laser beams to a scanned surface; a second optical mechanism arranged between the first optical mechanism and the light deflective reflection mechanism and having a negative power in at least a main scanning direction; and an aperture element configured to determine a beam spot diameter in the main scanning direction on the scanned surface and arranged between the light source and the light deflective reflection mechanism and between a last stage optical element of the first optical mechanism and a first stage optical element of the second optical mechanism.
