Provided is a toner set that has excellent fine line reproducibility and color reproducibility when different types of toner are printed in a superimposed manner. The toner set includes a yellow toner, a cyan toner, and a magenta toner that each contain: colorant resin particles comprising a binder resin, a colorant, and a charge control agent; and an external additive. The toner set is characterized in that: the average absolute value of (q/d) for each of the yellow toner, the cyan toner, and the magenta toner that is expressed from a charge amount (q) (in fC) and a particle size (d) (in µm) and that is determined by measurement using an electrical field jump-type charge amount distribution measurement device after a specific frictional charging treatment is 2.0-6.5 fC/10 µm; the standard deviation (SD) of (q/d) is 13 fC/10 µm or less; the difference (Δq/d) between the average values of (q/d) for two different types of toner from among the yellow toner, the cyan toner, and the magenta toner is 2.0 fC/10 µm or less; and the difference (ΔSD) between the standard deviations of (q/d) for two different types of toner from among the yellow toner, the cyan toner, and the magenta toner is 5.0 fC/10 µm or less. |
