Abstract: An image forming apparatus includes light sources, a light intensity controller, an optical writing unit, a controller, and an image forming unit. The light sources are switchable between activated and deactivated conditions according to supplied image data. The light intensity controller controls light intensity of the light sources. In the optical writing unit, light beams output from the light sources are deflected in a main scanning direction. The controller sets a given number of light sources to activated condition to write a latent image on an image bearing member according to an image forming line speed. The controller instructs the given number of light sources to emit light beams onto an image area on the image bearing member, and instructs all of the light sources to emit light beams at a blank area on the image bearing member to execute a light intensity control for all of the light sources.
