PROBLEM TO BE SOLVED: To provide a high quality image reduced with a density variation by executing smooth shading correction matched with optical characteristics without making a device configuration excessive. SOLUTION: An image forming apparatus that executes shading correction includes: an LD driver 312 for driving a light source that emits a light beam; and a light-quantity-adjustment-amount control unit 345 for executing adjustment of a light quantity in accordance with a shading correction curve by controlling the light-quantity adjustment amount and increase/decrease cycle of the light-quantity adjustment amount to the LD driver 312.
