PROBLEM TO BE SOLVED: To provide a three-dimensional coloring apparatus which can appropriately color three-dimensional objects. SOLUTION: This three-dimensional coloring apparatus 1 is provided with a stepping motor 26 for rotating the three-dimensional object 9 via a timing belt 24, an ink nozzle 31 for sequentially discharging a coloring ink and a control part 10 for controlling these stepping motor and ink nozzle. In controlling coloring to the three-dimensional object 9, with the ink discharged from the ink nozzle 31 at a constant timing, a rotational speed of the three-dimensional object 9 is adjusted in accordance with a distance from a rotational axis Kc to a surface of the three-dimensional object 9. Ink dot intervals Ga and Gb are made uniform, so that a density of images to be colored can be unified. In consequence, the three-dimensional object can be colored appropriately.
