摘要： A toner comprising a binder resin is provided. When the toner is observed with an atomic force microscope in tapping mode to obtain a phase image and the phase image is binarized with an intermediate value between maximum and minimum phase difference values in the phase image to obtain a binarized image, the binarized image consists of first phase-contrast portions having a large phase difference and second phase-contrast portions having a small phase difference, where the first phase-contrast portions are dispersed in the second phase-contrast portions and a dispersion diameter of the first phase-contrast portions is in a range of from 150 to 500 nm. The toner has at least two glass transition temperatures (Tg) in respective ranges of from 40° C. to 65° C. and from −30° C. to 20° C., determined from a DSC curve obtained at a first temperature rise in a differential scanning calorimetric measurement by a midpoint method.
