ABSTRACT:
An optical beam scanning device of the present invention is for having a light beam with the width in the main scanning direction wider than the width in the main scanning direction of the reflection surface of a deflector incident on the deflector, reflecting and polarizing a part thereof by the reflection surface of the deflector, and focusing the polarized light beam on a surface to be scanned by optical means including a transmission type optical member. Then, the polarization direction of the light beam incident on the deflector is substantially in the main scanning direction. According to an image forming apparatus comprising a plurality of light sources for forming a plurality of scanning lines with the light beams from a plurality of the light sources, the polarization direction of the light beams from the light sources at the time of being incident on the corresponding deflector is provided substantially in the main scanning direction.
