ABSTRACT:
A toner including toner particles comprising a binder resin; and at least two kinds of particulate resins which are located on at least a surface of the toner particles, wherein the toner satisfies at least one of the following relationships (TgA−TgB)≧20° C., wherein TgA and TgB represent glass transition temperatures (Tg) of a particulate resin (A) having a highest Tg and a particulate resin (B) having a lowest Tg among the at least two kinds of particulate resins, respectively; and 100,000≦Mwc≦6,000,000 and 8,000≦Mwd≦800,000, wherein Mwc and Mwd represent weight average molecular weights (Mw) of a particulate resin (C) having a highest Mw and a particulate resin (D) having a lowest Mw among the at least two kinds of particulate resins, respectively, wherein Mwc>Mwd.
