Abstract:
1. An optical-writing control device that controls light sources to form electrostatic latent images on photosensitive elements, the light sources and the photosensitive elements being provided on a per-color basis of different colors, the optical-writing control device comprising: a light-emission control unit that controls each of the light sources based on information on pixels constituting an image to be formed, thereby exposing each of the photosensitive elements to light; a detection-signal acquiring unit that acquires a detection signal output from a sensor on a conveying path where developing-agent images obtained by developing the electrostatic latent images formed on the photosensitive elements using developing agents of the different colors are transferred and conveyed; and a correction-value calculating unit that calculates correction values for use in correcting a transfer position at which the developing-agent images are to be transferred onto a sheet, overlaying positions at which the developing-agent images of the different colors are to be overlaid on one another, and densities of the developing-agent images based on the detection signal output from the sensor upon detection of a correction pattern for use in correcting the transfer position, a correction pattern for use in correcting the overlaying positions, and a correction pattern for use in correcting the densities, wherein
