Abstract

A composite core of a toner particle is a composite of a toner core containing a polyester resin and a plurality of resin particles each containing a first resin. A shell layer partially covering a surface of the composite core is a film containing a second resin. The first resin has a glass transition point that is 10° C. or more higher than a glass transition point of the second resin. The plurality of resin particles each have a particle diameter that is 1.5 times or more greater than a thickness of the shell layer. An amount of the resin particles is at least 0.3 parts by mass and no greater than 2.0 parts by mass relative to 100 parts by mass of the toner cores. The resin particles have a positive zeta potential at pH 4.
