A brilliant toner includes a toner particle including a binder resin and a flake-shaped brilliant pigment, wherein an amount of a portion insoluble in toluene except for an inorganic substance in the brilliant toner is from 4% by weight to 30% by weight with respect to a total amount of the brilliant toner.

A part material for printing three-dimensional parts with an electrophotography-based additive manufacturing system, the part material including a composition having an engineering-grade thermoplastic material and a charge control agent. The part material is provided in a powder form having a controlled particle size, and is configured for use in the electrophotography-based additive manufacturing system having a layer transfusion assembly for printing the three-dimensional parts in a layer-by-layer manner.
