In an optical scanning apparatus, when it is assumed that a scanning direction of light beams defected from a deflector (5) is a main scanning direction, and a direction orthogonal to the main scanning direction and to optical axes of both a first and a first optical systems (2, 3, 4, 11, 10, 6, 7, 8) is a sub scanning direction, a distance between the outermost light emitting diodes of a light source (1) in the main scanning direction is longer than that in the sub scanning direction.
