Claim:
1. A toner comprising toner particles, each of which has a surface layer that contains an organosilicon polymer, the organosilicon polymer having a substructure represented by formula (T3) where R represents an alkyl group having 1 to 6 carbons or a phenyl group, wherein a ratio ST3 of the peak area for the substructure represented by formula (T3) to the total peak area for the organosilicon polymer in a a silicon atom concentration dSi with reference to a total concentration (dC+dO+dSi) of the silicon atom concentration dSi, an oxygen atom concentration dO, and a carbon atom concentration dC in electron spectroscopy for chemical analysis of a surface of the toner particles is 2.5 atom % or more.
