ABSTRACT:
There is provided a toner having favourable development characteristics and favourable stability and a method for production thereof. The toner comprises at least a graft copolymer and a coloring material, wherein the graft copolymer is formed by graft polymerization of a polymerizable monomer with a block copolymer having a polymerizable functional group on a side chain. The method for producing the toner has a step of subjecting a reaction mixture comprising at least a block copolymer having a polymerizable functional group in a side chain and having a polyalkenyl ether repeating unit structure, a polymerizable monomer, and a coloring material to suspension polymerization or emulsion polymerization, to produce a graft copolymer in which a polymer of the polymerizable monomer is grafted to the side chain of the block copolymer.
