Claim 0:
1. 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.
