Abstract
An optical scanning apparatus includes a plurality of light sources capable of emitting light. A detection unit detects a light quantity of the light emitted from the plurality of light sources. A control unit controls drive current of a light source designated as a control object based on a detection result obtained by the detection unit. The control unit controls the drive current based on an activation state of the light source designated as the control object and an activation state of a light source other than the control object.
