A toner characterized by improved fixingnperformances with no or minimum oil application isnformed of: (i) a binder resin, (ii) a colorant, (iii)na hydrocarbon wax, (iv) a resin composition formed byncopolymerization of a styrenic monomer together withnat least one of nitrogen-containing vinyl monomers,ncarboxyl group-containing monomers, hydroxyl group-containingnmonomers and (meth)acrylate ester monomers,nin the presence of a hydrocarbon unit; and (v) annorganometallic compound. The binder resin (i)ncomprises a polyester component in a proportion of atnleast 60 wt. % of the binder resin. The toner has anGPC molecular weight distribution including a weight-averagenmolecular weight (Mw) of at least 4.0x10 4 an anratio Mw/Mn of at least 50 between the Mw and annumber-average molecular weight (Mn). |
