More Information
Summary:Provided is a toner which is less likely to generate toner agglomerates, exhibits stable charging performance regardless of the use environment, and has little fluctuation in charging performance even during continuous mass printing. The toner includes toner particles containing a binder resin and silica fine particles S1, in which the toner has a weight average particle diameter of 4.0 [mu] m or more and 15.0 [mu] m or less, including two end points. In a 29Si-NMR measurement of silica fine particles S1, a peak derived from the silica fine particles S1 is observed, and in a spectrum obtained by 29Si CP/MAS NMR or 29Si DD/MAS NMR, a peak derived from the silica fine particles S1 is observed. The peak area of the peak corresponding to the D1 unit structure in the silica fine particles S1, the peak area of the peak corresponding to the D2 unit structure in the silica fine particles S1, and the peak area of the peak corresponding to the Q unit structure in the silica fine particles S1 satisfy a predetermined rel
