Patent ID: 11599035

Abstract:
A toner having a toner particle including a toner base particle and an organosilicon polymer coating the toner base particle, wherein when S1 (μm2) is a total area of a non-coated part not coated with the organosilicon polymer on an outermost surface of the toner particle, S2 (μm2) is a total area of a coated part coated with the organosilicon polymer on the outermost surface of the toner particle, and SA1 (μm2) is a total of areas of non-coated part domains D1 with an area of not more than 0.10 μm2 in size in the non-coated part not coated with the organosilicon polymer, formulae (1) and (2) below are satisfied. 0.45≤[S2/(S1+S2)]≤0.65  (1)(SA1/S1)≥0.50  (2)
