Abstract:
A toner comprising: (i) a binder resin, (ii) a colorant, (iii) a hydrocarbon wax, (iv) a resin composition comprising at least a copolymer unit synthesized by reaction of a styrenic monomer with at least one monomer selected from the group consisting of nitrogen-containing vinyl monomers, carboxyl group-containing monomers, hydroxyl group-containing monomers, acrylate ester monomers and methacrylate ester monomers, and a hydrocarbon unit; and (v) an organometallic compound;wherein the binder resin (i) comprises a polyester component in a proportion of at least 60 wt. % of the binder resin (i), and the toner has a molecular weight distribution as measured by gel permeation chromatography (GPC) including a weight-average molecular weight (Mw) of at least 4.0Ã—104 and a ratio Mw/Mn of at least 50 between the weight-average molecular weight (Mw) and a number-average molecular weight (Mn).
