Abstract: A toner comprising a toner particle comprising: a toner base particle; and an organosilicon polymer at a surface of the toner base particle, wherein protruded portions constituted from the organosilicon polymer are present at the surface of the toner base particle, when a specific reciprocating shaking test is carried out, the toner particle is measured in terms of a total area S of a surface of the toner particle and an area Sc of regions of the surface of the toner base particle coated with the organosilicon polymer at the surface of the toner particle before and after the test, values of Sc/S for the toner particle before and after the test are respectively defined as R0 and R1, the value of R0 is 0.30 to 0.70, a value of (R0?R1)/R0 is 0.20 or less, and a storage elastic modulus at 100° C. of the toner is 8000 to 50,000 Pa.

Abstract: A toner comprising a toner particle comprising: a toner base particle comprising a binder resin; and an organosilicon polymer at a surface of the toner base particle, wherein protruded portions constituted from the organosilicon polymer are present at the surface of the toner base particle, when a protruded portion having a height of 30 to 200 nm among the protruded portions is defined as a protrusion x, and the protrusion x is observed in a specific condition using a scanning electron microscope, an average aspect ratio of the protrusion x is 1.3 or more, and when shape measurements of a specific region of the surface of the toner particle are carried out using an atomic force microscope and measured data obtained by observing the protruded portions at the surface of the toner particle is subjected to surface roughness analysis, an average angle of inclination ?a is 1.0 to 2.0°.
