Abstract
A toner set for electrostatic image development includes a cyan toner, a magenta toner, and a yellow toner, wherein the Vicat softening temperatures of the toners are respectively in the range of from about 30° C. to about 60° C., and among the toners, the difference between the Vicat softening temperature of the toner having the highest Vicat softening temperature and the Vicat softening temperature of the toner having the lowest Vicat softening temperature is from about 1° C. to about 5° C.
