Patent ID: 7335453

Claim:
A toner composition comprising: a branched amorphous sulfonated polyester resin; and a crystalline sulfonated polyester resin; wherein the toner composition possesses a Newtonian loss modulus (G″) of about 60,000 to about 120,000 Pascal at a temperature of about 65° C. to about 80° C. at a shear rate of about 0.05 to about 0.5 hertz and a G″ of about 30 to about 400 Pascal at a temperature of about 150° C. to about 165° C. at a shear rate of about 0.05 to about 0.5 hertz; and wherein the toner composition possesses a storage modulus (G′) of about 40,000 to about 90,000 Pascal at a temperature of about 65° C. to about 80° C. at a shear rate of about 0.05 to about 0.5 hertz and a G′ of about 10 to about 130 Pascal at a temperature of about 150° C. to about 165° C. at a shear rate of about 0.05 to about 0.5 hertz.
