PROBLEM TO BE SOLVED: To provide a resin emulsion which is readily emulsified even when using a crosslinked polyester as the resin, and is substantially free from hydrolysis of the resin and can produce a toner having an excellent heat-resistant storage property, a process for producing the resin emulsion, and a toner for electrophotography which is obtained by using the resin emulsion, and is excellent in the heat-resistant storage property, and the process for producing the same. SOLUTION: The resin emulsion is produced by neutralizing a resin binder containing acid group with a basic compound in an aqueous medium wherein the resin binder containing acid group contains a polyester produced from a raw monomer composition containing a trivalent or higher-valent polyhydric alcohol in an amount of 1 to 15 mol%. The process for producing the resin emulsion, and the toner for electrophotography using the resin emulsion are provided. COPYRIGHT: (C)2008,JPO&INPIT
