摘要:
A toner is provided that comprises a toner particle comprising a binder resin and a wax, and an inorganic fine particle on a surface of the toner particle, wherein the binder resin comprises a resin A; the toner satisfies 2.50≤SPa-SPw≤4.50, where SPa (cal/cm 3 ) 0.5 is the SP value of the resin A, and SPw (cal/cm 3 ) 0.5 is the SP value of the wax; the inorganic fine particle comprises a silica fine particle whose surface has been treated with a silicone oil; in a 29 Si solid-state NMR measurement of the silica fine particle, 30≤B≤60 and 4.0≤A/B≤6.0 are satisfied, taking A as an integration value of a D unit obtained by taking an integration value of a Q unit in a CP/MAS measurement as 100, and taking B as an integration value of a D unit obtained by taking an integration value of a Q unit in a DD/MAS measurement as100.
