Abstract
An optical disk image forming apparatus that forms an image on an optical disk, comprises: an optical disk drive that includes a rotating unit for rotating an optical disk and a laser light irradiating unit being movable in a radial direction of the optical disk; and a control unit that sets a plurality of pixel areas on the optical disk, allocates predetermined writing densities to the plurality of pixel areas, respectively, and controls the optical disk drive to irradiate the laser light onto each pixel area according to the allocated writing densities. When the allocated writing density is a halftone writing density, the control unit corrects the halftone writing density so as to be lighter darker than the allocated writing density.
