Abstract:
A scanning path of light includes a synchronization detection area A where a synchronization detection sensor  47  detects scanning light and an image writing area B where writing of the image data to a photosensitive drum  11  is performed by the scanning light, and a light amount change unit  100  is configured to reduce a change amount of a light amount in the synchronization detection area A as compared with the image writing area B.

Claim (Index 1):
An optical scanning device comprising:\n a light source that emits light; a deflector that deflects the light emitted from the light source and allows the deflected light to be scanned on a surface of a photosensitive drum; a synchronization detection sensor provided at a predetermined position of a scanning path of the light deflected by the deflector and outputting a reference signal of a writing start timing of image data to the photosensitive drum; a scanning control unit that controls a scanning speed of the light by the deflector in accordance with a printing condition; and a light amount change unit that changes a light amount of the light source such that the light amount of the light source is increased as the scanning speed of the light by the deflector is high, wherein the scanning path of the light includes a synchronization detection area where the synchronization detection sensor detects scanning light and an image writing area where writing of the image data to the photosensitive drum is performed by the scanning light, and the light amount change unit is configured to reduce a change amount of the light amount in the synchronization detection area as compared with the image writing area.
