ABSTRACT:
A toner for electrophotography and a process for producing the same are disclosed. The toner is formed from particles which are formulated from at least a cured composition which contains at least a binder resin having an unsaturated double bond, and can also contain a reactive monomer, a radical-polymerization catalyst, and a catalyst. The resulting particles each have a crosslinking density that gradationally increases from the center towards the surface of the particle. The toner of the present invention is fixable at low temperatures, has no problems associated with storage stability in practical use, and can be firmly fixed to receiving paper.
