Abstract
An image forming apparatus includes: a scanning unit configured to form latent images in a first region and in a second region of the photoreceptor; and a control unit configured to control a light emission luminance of the scanning unit. The control unit is further configured to set the light emission luminance of the scanning unit to a first light emission luminance when scanning of the first region is started, and set the light emission luminance of the scanning unit to a second light emission luminance higher than the first light emission luminance when scanning of the second region is started, and to decrease the light emission luminance of the scanning unit while the second region is being scanned, in a case where the second region is an upstream side of the first region in the scanning direction.
