PURPOSE: To provide an electrophotography toner, which is excellent in humidity resistance, a charging properly, and repeatability and provides sufficient image density, and a manufacturing method for the electrophotography toner. CONSTITUTION: In an electrophotography toner prepared by means of polymerization of polymerizing monomers and in a manufacturing method for the toner, if filtrate with conductivity D2 is provided after filtration of the polymer toner when the polymer toner is dispersed in water with conductivity D1 at a rate of toner to water 1g/20ml and they are sufficiently stirred so as to be brought into a balanced condition, such a relationship as 5μS/cm
