An optical scanning apparatus (10) according to one aspect of this invention includes a light source (43) that outputs a light beam having a light power based on a supplied driving current, a detection unit (PD) that detects the light power of the light beam, and a voltage holding unit (505) that holds a charged voltage to be used to control the driving current. The optical scanning apparatus further includes a control unit (31, 403) that controls a charging unit (501-504) so that the voltage holding unit is charged in a state where the driving current is not supplied to the light source, and controls the charging unit based on a detection result of the detection unit so that the voltage held in the voltage holding unit is controlled from the voltage of the voltage holding unit charged in the state where the driving current is not supplied to the light source. |
