  • Patent number: 9098796
    Abstract: An image forming device has an image processing unit that generates first image data on the basis of image forming data describing an object. The first image data specify first gradation values of at least one black or chromatic color. The image processing unit also identifies certain pixels in an area in which the object is disposed, and generates second image data specifying a second gradation value that is greater than a predetermined gradation value for the identified pixels. An image forming unit forms a first image, based on the first image data, by using at least one black or chromatically colored developing agent, and forms a second image, based on the second image data, by using a white developing agent, thereby reproducing colors in white areas while reducing the usage of the white developing agent.
