Abstract

A toner comprising a toner particle that contains a binder resin and fine particles A at the surface of the toner particle, wherein the fine particles A are organosilicon polymer fine particles, the organosilicon polymer fine particles have a number-average primary particle diameter of 30 nm to 500 nm, the organosilicon polymer fine particles have an attachment index for a polycarbonate film of not more than 3.5, the organosilicon polymer fine particles penetrate into the toner particle in a penetration depth b (nm), and protrude from the toner particle in a protrusion height c (nm), and b and c satisfy 0.05 ≤ b/(b + c) ≤ 0.40.
