    摘要: A toner includes a binder resin including a copolymer resin containing structural units derived from crystalline and non-crystalline resins, respectively. Spin-spin relaxation time (t50) of the toner at 50° C. measured by pulse NMR is ≦0.05 msec., spin-spin relaxation time (t130) at 130° C. when warmed from 50° C. to 130° C. is >15 msec., and spin-spin relaxation time (t′70) at 70° C. when cooled from 130° C. to 70° C. is ≦1.00 msec. A binarized image obtained by binarizing a phase image of the toner observed by a tapping mode AFM based on intermediate value between maximum and minimum phase difference values in the phase image includes first phase difference images constituted by large phase-difference portions and a second phase difference image constituted by a small phase-difference portion. The first phase difference images are dispersed in the second phase difference image. The dispersion diameter of the first phase difference images is 150 nm or less.

    摘要: A toner includes a binder resin including a copolymer resin (A) having a structural unit derived from a crystalline polyester resin (A1) and another structural unit derived from an amorphous polyester resin (A2), and an amorphous resin (B) in an amount of from 30 to 70% by weight based on total weight of the binder resin. The binarized image of the AFM phase image of the binder resin consists of first phase-contrast images serving as large-phase-difference portions and second phase-contrast images serving as small-phase-difference portions with the first phase-contrast images dispersed in the second phase-contrast images forming a dot-like or streaky structure. The average value of dispersion diameters, corresponding to maximum Feret diameters, of the first phase-contrast images in the dot-like structure, or widths, corresponding to minimum Feret diameters, of the first phase-contrast images in the streaky structure, is less than 100 nm.
