Claim 0:
1. A scanning optical apparatus comprising:
a first light source unit provided with a first light source and a cylindrical first holding member for holding said first light source;
a second light source unit provided with a second light source and a cylindrical second holding member for holding said second light source;
a deflection unit provided with a rotary polygon mirror for deflecting laser beams emitted from said first light source and said second light source; and
a casing provided with a bottom surface on which said deflection unit is disposed,
wherein said second light source unit is disposed further from the bottom surface than said first light source unit with respect to a rotational axis direction of said rotary polygon mirror,
wherein said casing is provided with a first supporting surface for supporting said first light source unit and a second supporting surface for supporting said second light source unit,
wherein both the first supporting surface for supporting said first light source unit and the second supporting surface for supporting said second light source unit are faced in a direction opposite to a direction facing the bottom surface, and are faced in the same direction as each other,
wherein said first light source unit and said second light source unit are mounted to the first supporting surface and the second supporting surface corresponding to said first light source unit and said second light source unit in the same direction along the rotational axis direction, and
wherein said first light source unit is mounted to the first supporting surface through a mounting space for said second light source unit, and said second light source unit is mounted to the second supporting surface without passing through a mounting space for said first light source unit.
