PROBLEM TO BE SOLVED: To provide a toner excellent in environmental stability, low-temperature fixability, development durability and storage stability. A toner having toner particles having a surface layer containing an organosilicon polymer, The organosilicon polymer has a specific partial structure, and has an average thickness Dav. In the mapping measurement using the FIB-TOF-SIMS, the toner has a specific ratio of silicon ions and carbon ions released from the toner particles when the surface of the toner particles is irradiated with primary ions. .
