Abstract:
Provided is a resin for a toner, which is a copolymer including a crystalline segment, and having a maximum elastic stress value at 100° C. (ES100) of 1,000 Pa or less, and a maximum elastic stress value at 70° C. (ES70) of 1,000 Pa or greater when the temperature is lowered from 100° C. to 70° C., where the maximum elastic stress values are measured according to a large amplitude oscillatory shear procedure.
