An apparatus and method of manufacturing a white dry ink pulverized toner including a resin and 15%-45% TiO2 pigment having a mean size of 100-350 nm melt mixed with the resin in a twin screw extruder resulting in an extruded mix. The extruded mix is pulverized in a fluid bed jet mill. Fines of the pulverized extruded mix less than 5 microns may be removed from the pulverized extruded mix by classification leaving pulverized particles having a mean size of 6-12 microns. The pulverized particles are blended in a mixer with surface additives including silica and ZnSt, and the white dry ink pulverized toner has a developer charge between 5 and 50 &#x3bc;C/gram and a Lightness (L*) of at least 75 at a toner mass per unit area (TMA) of at most 1.2 mg/cm.

White dry ink pulverized toner composition and formulation thereof

A toner composition including a toner particle having a surface, wherein the toner particle comprises at least one toner resin; a metallic pigment bonded to the surface of the toner particle; and an insulative surface additive disposed over the metallic pigment.

Metallic toner compositions

Disclosed is a toner composition comprising: (a) a resin; and (b) a colorant which comprises: (1) Pigment Red 269; (2) Pigment Red 185; and (3) Pigment Red 122.
