PROBLEM TO BE SOLVED: To provide a nonmagnetic monocomponent color toner which satisfies optimum conditions with respect to a toner particle size distribution, which will not cause primary image defects, such as fog and cleaning defects, and is free from problems, such as rise in the image density and defacing of thin lines, even in a life time test of continuous printing. SOLUTION: The nonmagnetic monocomponent color toner is configured, in such a way that, in particle size distribution measurement controlled in a specified particle size range, among weight distribution average particle size W (μm), the number distribution average particle size N (μm) and distribution ratio a(%) in this particle size range to which the number distribution average particle size belongs, the relational expression: (N×a)/W≥30(%) is established.
