Abstract
A low melt toner includes a core having a core polystyrene-butyl acrylate resin, a crystalline polyester resin, a pigment present in an amount from about 7% to about 20% by weight of the low melt toner, and a paraffin wax; a ratio of the polystyrene-butyl acrylate resin to crystalline polyester resin is in a range from about 5:1 to about 7:1; and a shell disposed over the core including a shell polystyrene-butyl acrylate resin.
