    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.
