Abstract
A toner comprising a toner particle comprising a binder resin and organosilicon polymer particles on a surface of the toner particle, wherein the binder resin comprising an amorphous resin and a crystalline polyester resin, an absolute value |SPcpes−SPsi| of a difference between an SP value (SPsi) of the organosilicon polymer particles and an SP value (SPcpes) of the crystalline polyester resin is not more than 2.00 (cal/cm3)1/2, and an amount of adsorbed water in the organosilicon polymer particles at a temperature of 30° C. and a humidity of 80% RH is not more than 20 mg/g.

A toner, comprising:
- a toner particle comprising a binder resin and organosilicon polymer particles on a surface of the toner particle;
- the binder resin comprising an amorphous resin and a crystalline polyester resin, wherein
- a concentration of methanol is 45 to 80 vol % when a transmittance of light with a wavelength of 780 nm is 50% in a wettability test of the organosilicon polymer particles using a mixed solvent of methanol/water,
- |SPcpes−SPsi| is not more than 2.00 (cal/cm3)1/2 where SPsi is an SP value of the organosilicon polymer particles and SPcpes is an SP value of the crystalline polyester resin, and
- an amount of adsorbed water in the organosilicon polymer particles at a temperature of 30° C. and a humidity of 80% RH is not more than 20 mg/g.
