<p>An image forming apparatus (100) that performs a shading correction includes a light source (200) that emits a light beam; a light-source drive unit (312) that drives the light source (200); and a light-quantity-adjustment-amount control unit (345) that performs an adjustment of a light quantity in accordance with a shading correction curve by controlling, for the light-source drive unit (312), a light-quantity adjustment amount and an increase/decrease cycle of the light-quantity adjustment amount. The increase/decrease cycle is a unit of time within a time period (T1; T1') during which the light-quantity adjustment amount increases or decreases.</p> |
