First claim
Opening claim text (preview).
We claim: 1. Emulsion aggregation toner particles comprising a magenta colorant comprising a BET surface area from about 75 m 2 /g to about 85 m 2 /g, wherein circularity of said toner particles is between about 0.9 and about 1.0, and said toner particles comprise improved J zone charge. 2. The toner particles of claim 1 , wherein volume diameter of said toner particles is at least about 5.53 μm. 3. The toner particles of claim 1 , wherein volume diameter of said toner particles is at least about 5.55 μm. 4. The toner particles of claim 1 , comprising a polyacrylate resin. 5. The toner particles of claim 1 , comprising a polystyrene resin. 6. The toner particles of claim 1 , comprising an amorphous resin, a crystalline resin or both. 7. The toner particles of claim 1 , comprising a polyester resin. 8. The toner particles of claim 1 , comprising a wax. 9. The toner particles of claim 1 , comprising a shell. 10. The toner particles of claim 1 , comprising a second colorant. 11. The toner particles of claim 1 , wherein said magenta colorant comprises 2,9-dimethyl-substituted quinacridone, CI 60710, CI Dispersed Red 15, CI 26050, CI Solvent Red 19 or PR 269. 12. The toner particles of claim 1 comprising from about 3 to about 15 wt % colorant. 13. The toner particles of claim 1 , comprising from about 2 to about 35 wt % colorant. 14. The toner particles of claim 1 comprising a low melt toner. 15. The toner particles of claim 1 , comprising a charge control agent. 16. The toner particles of claim 1 , comprising a flow aid. 17. The toner particles of claim 1 , comprising a silica. 18. The toner particles of claim 1 , comprising a metal oxide. 19. A developer comprising the toner particles of claim 1 . 20. The developer of claim 19 comprising a carrier.
