PROBLEM TO BE SOLVED: To make lines occurring in an image inconspicuous.SOLUTION: An image forming device includes: an LED array 41 in which LED array chips CH having a plurality of light emitting elements P are arranged side by side in a main scanning direction; a photoreceptor drum 53 which is exposed to light by the LED array 41; an image forming part 30 which forms an image on a recording medium by using an electrostatic latent image formed on the photoreceptor drum 53; and a controller U which corrects a light amount of the light emitting elements when using a dithering pattern expressing gradation of the image. The controller U uses a dot concentration type dithering pattern with a 4-dot cycle or more, and when distance Dx between elements between two light emitting elements located on an end part of the LED array chip CH is deviated from a reference pitch Dp, it corrects the light emitting element located on the second place and after from the end part of the LED array chip CH with a light amount correction value larger than a light amount correction value X1 of a first light emitting element P1 located in the first place. |
