Abstract:
1. A toner having a glass transition temperature (Tg) observed at least at one point from 25 to 65° C. in a differential scanning calorimeter at a rate of temperature increase of 5° C./min, and comprising: a binder resin having an amorphous composition and comprising: a crystalline resin, which is an aliphatic polyester, wherein the toner has a structure in which a high phase difference image corresponding to the polyester backbone B is dispersed a low phase difference image corresponding to the polyester backbone A in a two-dimensional phase difference image observed by tapping mode AFM, wherein an X-ray diffraction chart in which a peak originated from the crystalline resin is observed in a range of a diffraction angle 2θ of from 20 to 25°, and wherein a ratio (I1/ I2) of an intensity of the peak originated from the crystalline resin to an intensity (I2) of a halo originated from the amorphous composition is from 0.2 to 1.
