Abstract
The present invention provides a toner which does not cause problems on generation of an offensive odor and a stain on a surface of a cooling unit and which is excellent in an offset resistance, a low temperature fixability and an environmental dependency. In the toner for developing an electrostatic latent image comprising a polyester resin as a principal component which is formed by reacting dicarboxylic acids of a polybasic acid with diols of a polyhydric alcohol, dimethyl phthalate remaining in the polyester resin described above without reacting has a content of 0.1 % by weight or less.
