Abstract
An electrophotographic image forming apparatus comprising a photoreceptor, a conductive magnetic brush development system, and a housing in association with the conductive magnetic brush development system for a developer comprising a toner composition having emulsion/aggregation toner particles comprising a gel latex, a high Tg latex, a wax, and a colorant, wherein the wear rate of the photoreceptor is improved.

An electrophotographic image forming apparatus comprising a photoreceptor, a conductive magnetic brush development system, and a housing in association with the conductive magnetic brush development system for a developer comprising a toner composition having emulsion/aggregation toner particles comprising a gel latex, a high Tg latex, a wax, and a colorant,
- wherein the gel latex is present in an amount of from about 3 weight percent to about 30 weight percent of the toner composition, the high Tg latex is present in an amount of from about 50 weight percent to about 95 weight percent of the toner composition, the wax is present in an amount of from about 2 weight percent to about 40 weight percent of the toner composition, and the colorant is present in an amount of from about 1 weight percent to about 25 weight percent of the toner composition.
A developer comprising a carrier and an emulsion/aggregation toner, wherein the toner comprises a gel latex, a high Tg latex, a wax, and a colorant,
- wherein the gel latex is present in an amount of from about 3 weight percent to about 30 weight percent of the toner, the high Tg latex is present in an amount of from about 50 weight percent to about 95 weight percent of the toner, the wax is present in an amount of from about 2 weight percent to about 40 weight percent of the toner, and the colorant is present in an amount of from about 1 weight percent to about 25 weight percent of the toner, and
- wherein the developer is capable of reducing photoreceptor wear in a conductive magnetic brush development system.
A method of printing a toner based image, comprising:
- charging a photoreceptor to a uniform potential,
- exposing the charged photoreceptor surface to a light image in order to record an electrostatic latent image onto the surface of the photoreceptor,
- developing the electrostatic latent image by bringing a developer in contact with the electrostatic latent image to expose an image,
- transferring the image to a substrate to form a toner-based image, and
- fusing the toner-based image to the substrate,
- wherein the developer comprises an emulsion/aggregation toner having a gel latex, a high Tg latex, a wax, and a colorant,
- wherein residual toner is removed from the photoreceptor surface with a cleaning device, and
- wherein the wear rate of the photoreceptor is from about −0.004 μm/Kcycles to about −0.018 μm/Kcycles.
A developer comprising a carrier and a toner, wherein the developer has a photoreceptor wear rate rating of from about 0.004 μm/Kcycles to about −0.018 μm/Kcycles.
