摘要： The present invention relates to a toner for electrophotography including a polyester obtained by subjecting a crystalline polyester-containing aqueous dispersion and a non-crystalline polyester-containing aqueous dispersion to aggregation and coalescence, as a resin binder, wherein the crystalline polyester is produced by polycondensing an alcohol component containing 70 mol % or more of an aliphatic diol having 2 to 8 carbon atoms with a carboxylic acid component containing 50 mol % or more of terephthalic acid. The toner is excellent in low-temperature fusing ability and pressure storage stability.
