1. A light scanning apparatus comprising:
a deflection unit configured to deflect a first beam and a second beam from a light source unit, which includes a first light-emitting point which intermittently emits the first beam and a second light-emitting point which intermittently emits the second beam, along a main scanning direction; and an imaging optical system configured to focus the first beam and the second beam emitted from the deflection unit on a surface to be scanned so as to form a plurality of spots using the first beam and a plurality of spots using the second beam, wherein letting a first spot and a second spot be two neighboring spots of the plurality of spots formed by the first beam, and a third spot and a fourth spot be two spots of the plurality of spots formed by the second beam having the same positions as the first spot and the second spot in the main scanning direction, a time difference when the first light-emitting point emits the beam so as to form the first spot and the second spot and a time difference when the second light-emitting point emits the beam so as to form the third spot and the fourth spot are different from each other. |
