Claim:
A toner formed of aggregate of resin-containing particles which are obtained by finely granulating a slurry of amorphous resin particles containing a binder resin, a colorant, a release agent, and a release agent-dispersing aid using a high-pressure homogenizer method, the resin-containing particles having a volume average particle diameter in a range of from 0.4 μm to 1.0 μm, wherein the binder resin consists of a polyester resin, and the release agent-dispersing aid is selected from a styrene-ethylene-butadiene block copolymer, a styrene-methyl methacrylate block copolymer, an ethylene-styrene graft copolymer, maleic anhydride copolymer, and a copolymer of an α-olefin-maleic anhydride copolymer and maleic anhydride monoester.
