Abstract
The toner for developing electrostatic images, comprising: colored resin particles comprising a binder resin, a colorant and a release agent, and an external additive. The colored resin particles further comprise a styrene-based thermoplastic elastomer. The styrene-based thermoplastic elastomer comprises an isoprene unit. A content of a fatty acid ester compound having a number average molecular weight (Mn) of 500 or more and less than 2,000 as the release agent, is from 2 parts by mass to 20 parts by mass with respect to 100 parts by mass of the binder resin.
