Abstract
A control system controls an image forming unit that includes a charging device, an image bearer to be charged by the charging device, a light-emitting device array including a plurality of light emitting devices, and a driving causing the light emitting devices to emit light to form a latent image on the image bearer. The control system includes a storage unit, a corrector, and a controller. The storage unit is configured to store a light-amount correction value of each of the light emitting devices. The corrector is configured to correct a pixel value of each pixel in image data, based on the light-amount correction value of each light emitting device stored in the storage unit. The controller is configured to control the driver to cause each light emitting device to emit light based on image data for which a pixel value of each pixel has been corrected.
