A toner having a toner particle containing a resin component, wherein the resin component contains an olefin copolymer having ester group and the like, which has a unit (1), and a unit Y2 that is at least one selected from (2) and (3), the content of the copolymer in the resin component is at least 50 mass % with respect to the total mass of the resin component, and the content of the monomer unit Y2 is 3 to 35 mass % with respect to the total mass of the copolymer;

##STR00001## in formulas (1) to (3), R.sup.1, R.sup.2 and R.sup.4 each independently represent H or CH.sub.3, and R.sup.3 and R.sup.5 each independently represent CH.sub.3 or C.sub.2H.sub.5.

A support material toner particle for use in xerographic additive manufacturing includes a polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the T.sub.g of the PVA polymer to be within about 1 C. to about 20 C. of a desired build material toner T.sub.g. A xerographic toner system includes a build toner material and a support toner material, the support toner material includes a polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the T.sub.g of the PVA polymer to be within about 1 C. to about 20 C. of the build material toner T.sub.g. A method of making a support toner material includes blending polyvinyl alcohol with blend additives including a chitosan and polyvinylpyrrolidone and forming support toner particles after the blending step.

A process includes forming an emulsion comprising a monomer and a colorant, the colorant further including an anionic functional group and a lipophilic counter ion, and polymerizing the monomer to form a latex, the latex includes polymer nanoparticles having the colorant dispersed therein.
