<p>A toner composition is disclosed which contains the product of the mixture of resin particles and chargeable modified pigment particles. The chargeable modified pigment particles comprise at least one organic ionic group attached to the pigment particle and at least one amphiphilic counterion. The amphiphilic counterion has a charge opposite to that of the organic ionic group wherein said organic ionic group is a cationic group selected from -3-C 5 H 4 N(C 2 H 5 ) + , C 6 H 4 COCH 2 N(CH 3 ) 3 + , -C 6 H 4 COCH 2 (NC 5 H 5 ) + ,-3-C 5 H 4 N(CH 3 ) + , -C 6 H 4 CH 2 N(CH 3 ) 3 + , and -ArCH 2 NH 2 (CH 3 ) + , wherein Ar represents an aromatic group. Developer compositions containing the toner compositions of the present invention and methods of imaging are also described which use the toner compositions of the present invention.</p> |
