Abstract: [Object] To form a modeled object with high accuracy. [Solving Means] A powder transfer mechanism (16) laminates powder layers containing water-soluble powder as a main component one by one at a modeling portion (14). An inkjet line head (17) injects a water-based ink that dissolves the powder in an area of an uppermost layer of the powder layers laminated by the powder transfer mechanism (16), the area corresponding to a cross-sectional shape of a modeled object. Then, a heater (18) heats the powder for each layer of the powder layers. Further, the heater (18) heats the powder after the water-based ink is injected by the inkjet line head (17) or before the water-based ink is injected by the inkjet line head (17). The present invention can be applied to a modeling apparatus, for example.
