The amorphous polyester segment includes a condensation polymerization product between a carboxylic acid and an alcohol. The carboxylic acid includes both aliphatic and aromatic dicarboxylic acids. The toner deforms with a deformation rate of from 1.0% to 5.0% under a pressure of 100 gf at 40° C. and 80% RH. In a binarized image of an AFM phase image of the toner, first phase-contrast images serving as large-phase-difference portions are dispersed in second phase-contrast images serving as small-phase-difference portions, and the first phase-contrast images have a dispersion diameter of 100 nm or less. An endothermic quantity Q1 obtained in a first heating of DSC is from 10 to 50 J/g, and a ratio of an endothermic quantity obtained in the second heating Q2 to that in first heating Q1 is 0.65 or less.
