摘要： Provided is a three-dimensional object producing method that includes applying an object forming liquid to powder including a base material and an organic material to form a solidified product, and removing the powder deposited on the solidified product from the solidified product using a powder removal liquid including an organic solvent. The following formulae are satisfied RED of non-forming part 0.55. The forming part is a portion of the powder to which the object forming liquid is applied and RED of the forming part is a distance between HSP of the forming part and HSP of the organic solvent. The non-forming part is a portion of the powder to which the object forming liquid is not applied and RED of the non-forming part is a distance between HSP of the non-forming part and HSP of the organic solvent.

摘要： A powder for forming 3D objects includes a group of particles having an identical composition. The group of the particles includes 50% by mass or greater of aluminum. An oxygen content of the group of the particles is 950 ppm or less. A volume-based particle size frequency distribution of the powder for forming 3D objects has a peak top in a particle diameter range of 40 μm or greater and 70 μm or less, and a peak top in a particle diameter range of 10 μm or greater and 30 μm or less. A ratio (a frequency (%) of the peak top in the particle diameter range of 40 μm or greater and 70 μm or less)/(a frequency (%) of the peak top in the particle diameter range of 10 μm or greater and 30 μm or less) is 1.5 or greater.

摘要： Carrier for image forming includes a core material particle including a magnetic material and a coating layer disposed on the surface of the core material particle, the coating layer including a resin, carbon black, an inorganic particulate A, and an inorganic particulate B. The carbon black has a concentration gradient along a thickness direction of the coating layer with a concentration from high to low toward a surface of the coating layer while the inorganic particulate A has a concentration gradient along a thickness direction of the coating layer with a concentration from low to high toward the surface of the coating layer. The volume ratio of the carbon black is 0-30 percent at a depth range of 0.0-0.1 μm from the surface of the coating layer. The inorganic particulate A is electroconductive with a powder specific resistance of 200 Ω·cm or less.
