1. A three-dimensional modeling apparatus, comprising:

  • a stage on which a powder material is accumulated;

    a head to eject ink to the powder material on the stage;

    an adjustment mechanism to adjust a relative height of the stage and the head for each predetermined layer thickness so that a three-dimensional object is formed on the stage by the predetermined layer thickness;

    an ejection command means for causing the ink to be ejected from the head so that the powder material is colored a plurality of colors respectively corresponding to multilevel luminance information items in a multivalued image, the multivalued image being obtained by performing a multivalued processing of a luminance with respect to data of a two-dimensional image that is a cross-sectional image of a modeling target object, the multivalued processing being an at least two-valued processing; and

    a control means to control the adjustment mechanism and the ejection command means so that the multivalued image is drawn for each layer thickness.
