Abstract
A toner comprising an organosilicon polymer particle and a toner particle containing a binder resin and a wax, wherein the organosilicon polymer particle contains an organosilicon polymer, a part of silicon atoms in the organosilicon polymer has a T3 unit structure, a ratio of an area of peaks derived from silicon having the T3 unit structure relative to a total area of peaks derived from all silicon element contained in the organosilicon polymer particle is from 0.70 to 1.00 in 29Si-NMR measurement of the organosilicon polymer particle, a plurality of domains of the wax are present in a cross-section of the toner particle, the wax is an ester wax, the average long diameter of the domains of the ester wax is from 0.03 μm to 2.00 μm, and the SP value SPw of the wax is from 8.59 to 9.01.
