PROBLEM TO BE SOLVED: To provide a toner that has excellent development durability and storage stability, and provide a toner that can provide a high-quality image in which the occurrence of rear-end offset of a high-printing ratio image is suppressed in a high-temperature and high-humidity environment.SOLUTION: There is provided a toner comprising toner particles containing a binder resin and a magnetic material, where the toner particles each include, on its surface, an organosilicon polymer having a partial structure represented by the following formula (T3): R-Si(O), where R represents an alkyl group and phenyl group having 1 to 6 carbon atoms; inSi-NMR measurement of a tetrahydrofuran insoluble in the toner particle, the ratio ST3 of a peak area of the partial structure represented by the formula (T3) relative to the total peak area of the organosilicon polymer is 40% or more; and the thermal conductivity of the toner is 0.190 W/(m K) or more and 0.300 W/(m K) or less.SELECTED DRAWING: None |
