Abstract

The invention as described herein provides a toner comprising a polymeric binder obtainable by suspension polymerisation of a mixture of vinyl monomers including both styrene or a styrene derivative and a (meth) acrylic ester, and an acid vinyl monomer in an amount of 0.5 to 10 wt. % based on the total weight of the vinyl monomers, the polymerisation being carried out using a non-ionic dispersing agent and an azo initiator. The toner of the present invention produces copied images having excellent stability of image quality (life) even after a large number of times of copying.
