Abstract:
In an optical scanning device, a light source includes a first light emitting point of an amount of light corresponding to a first mode and a second light emitting point of an amount of light corresponding to a second mode, and a control unit uses light beams emitted from a light emitting point of an amount of light corresponding to a mode set by a setting unit when the writing of image data is performed and uses light beams emitted from one prescribed light emitting point as light beams for synchronization detection, regardless of the mode set by the setting unit, when synchronization detection is performed before the writing of the image data is started.

Claim (Index 1):
An optical scanning device comprising:\n a light source; an optical deflector that deflects light beams emitted from the light source; a synchronization detection sensor that detects the light beams, which are scanned in a main scanning direction by the optical deflector, out of an image formation region of a surface to be scanned; a setting unit that switches and sets a first mode in which an amount of light of the light source is at a predetermined level and the second mode in which the amount of light of the light source is at a level lower than the predetermined level; and a control unit that receives a signal from the synchronization detection sensor, decides a writing start timing of image data, and controls the light source according to a mode set by the setting unit, thereby performing a writing process of the image data, wherein the light source includes a first light emitting point of an amount of light corresponding to the first mode and a second light emitting point of an amount of light corresponding to the second mode, and the control unit is configured to use light beams emitted from a light emitting point of an amount of light corresponding to the mode set by the setting unit between the first light emitting point and the second light emitting point when the writing of the image data is performed, and to use light beams emitted from prescribed one of the first light emitting point and the second light emitting point as light beams for synchronization detection, regardless of the mode set by the setting unit, when synchronization detection is performed before the writing of the image data is started.
