摘要: The toner is resistant to the generation of toner clumping, exhibits a stable charging performance regardless of the use environment, and exhibits little fluctuation in charging performance even during continuous high-print-count printing. The toner contains binder resin-containing toner particles and silica fine particles S 1, wherein the weight-average particle diameter of the toner is 4.0-15.0 µm, both inclusive. Peaks originating with the silica fine particles S1 are observed in 29 Si-NMR measurement of the silica fine particles S 1, and, in the spectrum obtained by 29 Si CP/MAS NMR or 29 Si DD/MAS NMR, the peak area of a peak corresponding to the D1 unit structure in the silica fine particles S 1, the peak area of a peak corresponding to the D2 unit structure in the silica fine particles S 1, and the peak area of a peak corresponding to the Q unit structure in the silica fine particles S 1 satisfy a prescribed relationship.
