ABSTRACT:
A toner for developing an electrostatic image comprises: a binder resin; and a releasing agent, wherein the binder resin comprises a polycondensation resin obtained by polycondensing a polycondensation monomer in the presence of a polycondensation catalyst, the releasing agent comprises a condensation compound obtained by condensing a condensation monomer in the presence of a condensation catalyst, the toner contains a metallic element derived from the polycondensation catalyst and the condensation catalyst in an amount of from 0 to 10 ppm, and the toner contains a sulfur component in an amount of from 100 to 20,000 ppm.
