Abstract
An electrostatic-image developing toner contains toner particles, each including a core particle and a shell layer disposed on at least a portion of a surface of the core particle. The core particle contains a first amorphous polyester resin containing structural units derived from a polycarboxylic acid and structural units derived from a polyol. About 5% by mass or less of the structural units derived from the polyol are structural units derived from a polyol containing a bisphenol-A backbone. The shell layer contains a second amorphous polyester resin containing structural units derived from a polycarboxylic acid and structural units derived from a polyol. About 50% by mass or more of the structural units derived from the polyol are structural units derived from a polyol containing a bisphenol-A backbone. The electrostatic-image developing toner has a water content of about 2.0% to about 5.0% by mass.
