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： 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 carrier for forming an electrophotographic image is provided. The carrier comprises carrier particles each comprising a core particle and a coating layer. The coating layer comprises a coating resin and inorganic particles comprising chargeable particles A and conductive particles B. The amount of the inorganic particles is from 195 to 350 parts by mass with respect to 100 parts by mass of the coating resin. The carrier particles consist of small carrier particles (D1≤25 μm), medium carrier particles (25 μm
