A writing devices for an image forming apparatus of the present invention determines whether or not an image at and around an interval between nearby light emitter chips of a light emitter array is of halftone. If the image is of halftone, the writing device corrects image data corresponding to the above interval in order to increase the quantity of light. This successfully reduces or fully obviates the local omission of an image ascribable to intervals between nearby light emitter chips and insures a smooth output image.
