Abstract

The present disclosure provides toners having a tunable gloss level, electrophotographic apparatuses for using such toners as well as processes for making such toners.

Claims (45)

1. An apparatus comprising:

a first developer station including at least one glossy toner;

a second developer station including at least one matte toner;

photoreceptor; and

a print controller configured to control the first and second developers to apply an amount of the at least one glossy toner and the at least one matte toner to said photoreceptor for transfer of an image thereon to an image receiving medium to obtain a blended toner having a gloss level from about 5 ggu to about 90 ggu, wherein toner gloss is dependent on aluminum content.

2. The apparatus according to claim 1 , wherein the at least one glossy toner has an aluminum content from about 20 ppm to about 200 ppm.

3. The apparatus according to claim 1 , wherein the at least one matte toner has an aluminum content from about 500 ppm to about 1000 ppm.

4. The apparatus according to claim 1 , further comprising:

a user interface configured to display at least one ratio of the at least one glossy toner and the at least one matte toner and to transmit a selected ratio to the print controller.

5. The apparatus according to claim 4 , wherein the user interface is configured to display a selection matrix of a plurality of ratios of the at least one glossy toner and the at least one matte toner.

6. The apparatus according to claim 1 , the blended toner includes the at least one glossy toner and the at least one matte toner at a weight ratio from about 10:90 to about 90:10.

7. The apparatus according to claim 1 , wherein each of the at least one glossy toner and the at least one matte toner comprises: at least one amorphous resin; at least one crystalline resin; at least one ionic crosslinker; optionally, at least one chelating agent; and optionally, one or more ingredients selected from the group consisting of waxes, coagulants, and combinations thereof.

8. The apparatus according to claim 7 , wherein the at least one ionic crosslinker is selected from the group consisting of aluminum sulfate, polyaluminum chloride, polyaluminum sulfosilicate, and combinations thereof and the at least one chelating agent selected from the group consisting of ethylene diamine tetra acetic acid (EDTA), L-glutamic acid N,N diacetic acid, humic acid, fulvic acid, peta-acetic acid, tetra-acetic acid, methylglycine diacetic acid, ethylenediamine disuccinic acid and salts and combinations thereof.

9. An imaging apparatus comprising:

a first developer station including at least one glossy toner;

a second developer station including at least one matte toner;

a photoconductive component of said imaging apparatus;

a user interface configured to display at least one ratio of the at least one glossy toner and the at least one matte toner; and

a print controller coupled to the user interface and configured to control the first and second developers to apply an amount of the at least one glossy toner and the at least one matte toner to said photoconductive component to form an image thereon, for transfer of said image to an image receiving medium to obtain a blended toner having a gloss level from about 5 ggu to about 90 ggu, wherein toner gloss is dependent on aluminum content.

10. The apparatus according to claim 9 , wherein the user interface is configured to display a selection matrix of a plurality of ratios of the at least one glossy toner and the at least one matte toner.

11. The apparatus according to claim 9 , wherein the at least one glossy toner has an aluminum content from about 20 ppm to about 200 ppm.

12. The apparatus according to claim 9 , wherein the at least one matte toner has an aluminum content from about 500 ppm to about 1000 ppm.

13. The apparatus according to claim 9 , Wherein each of the at least one glossy toner and the at least one matte toner comprises:

at least one amorphous resin; at least one crystalline resin;

at least one ionic crosslinker;

optionally, at least one chelating agent; and

optionally, one or more ingredients selected from the group consisting of waxes, coagulants, and combinations thereof.

14. The apparatus according to claim 13 , wherein the at least one ionic crosslinker is selected from the group consisting of aluminum sulfate, polyaluminum chloride, polyaluminum sulfosilicate, and combinations thereof and the at least one chelating agent selected from the group consisting of ethylene diamine tetra acetic acid (EDTA), L-glutamic acid N,N diacetic acid, humic acid, fulvic acid, peta-acetic acid, tetra-acetic acid, methylglycine diacetic acid, ethylenediamine disuccinic acid and salts and combinations thereof.

15. A method comprising:

displaying at least one selectable gloss level at a user interface;

transmitting a selected gloss level to a print controller; and

applying to a substrate at least one glossy toner stored in a first developer station and at least one matte toner stored in a second developer station, wherein said substrate comprises an image on a photoconductive component, to provide said image on an image receiving medium possessing, a gloss level from about 5 ggu to about 90 ggu, wherein toner gloss is dependent on aluminum content.

16. The method according to claim 15 , wherein the at least one glossy toner has an aluminum content from about 20 ppm to about 200 ppm.

17. The method according to claim 15 , wherein the at least one matte toner has an aluminum content from about 500 ppm to about 1000 ppm.

18. The method according to claim 15 , further comprising:

displaying at least one ratio of the at least one glossy toner and the at least one matte toner; and

transmitting a selected ratio to the print controller.

19. The method according to claim 15 , further comprising:

displaying a selection matrix of a plurality of ratios of the at least one glossy toner and the at least one matte toner; and transmitting a selected ratio to the print controller.

20. The method according to claim 15 , wherein each of the at least one glossy toner and the at least one matte toner includes:

at least one amorphous resin;

at least one crystalline resin;

at least one ionic crosslinker; and

optionally, at least one chelating agent; and

optionally, one or more ingredients selected from the group consisting of waxes, coagulants, and combinations thereof.
