Chemical toner

Abstract

A chemical toner composed of: (a) a resin including a compound which exhibits a molecular weight polydispersity of from about 1.1 to about 3.0; (b) an optional wax; and (c) a colorant, wherein the particle size of the chemical toner exhibits a geometric standard deviation of about 1.25 or less.

1 . A chemical toner comprising: 
 (a) a resin including a compound which exhibits a molecular weight polydispersity of from about 1.1 to about 3.0;    (b) an optional wax; and    (c) a colorant,    wherein the particle size of the chemical toner exhibits a geometric standard deviation of about 1.25 or less.    
     
     
         2 . The chemical toner of  claim 1 , wherein the geometric standard deviation ranges from about 1.18 to about 1.25.  
     
     
         3 . The chemical toner of  claim 1 , wherein the geometric standard deviation ranges from about 1.23 to about 1.25.  
     
     
         4 . The chemical toner of  claim 1 , wherein the compound exhibits a molecular weight polydispersity of from about 1.1 to about 2.0.  
     
     
         5 . The chemical toner of  claim 1 , wherein the compound exhibits a molecular weight polydispersity of from about 1.05 to about 1.45.  
     
     
         6 . The chemical toner of  claim 1 , wherein the resin is present in an amount of from about 65 to about 97 weight percent, the wax is present in an amount of from 0 to about 15 weight percent, and the colorant is present in the amount of 3 to about 15 weight percent based on the toner.
