Abstract:
A white toner for electrostatic charge image development contains a toner particle that includes a toner base particle containing a binder resin, a white colorant, and a releasing agent, and an external additive, wherein the toner particle contains, as the external additive, a fatty acid metal salt particle having a volume-based median diameter in a range of 0.5 to 1.5 μm, and an average circularity of the toner particles is in a range of 0.870 to 0.950.
