Abstract

See full text

An electrostatic-image developing toner includes toner particles each including a polyester resin and a styrene (meth)acrylic resin. In a micro-compression test where a load of 0.2 mN is applied to the toner particles at a loading rate of 0.098 mN/sec, the median of a distribution of the ratios (%) of deformations of the toner particles to the diameters of the toner particles is 8.0 or more and 18.0 or less, and a variation in the distribution of the ratios of deformations of the toner particles to the diameters of the toner particles is 0.02 or more and 0.40 or less.
