Developer compositions with toner compositions comprised of suspension polymerized styrene butadiene polymers, pigment particles, magnetites, and charge enhancing additives; and carrier components comprised of a carrier core with a coating thereover comprised of a polymer mixture with from about 10 to about 90 percent by weight of a first polymer, and from about 90 to about 10 percent by weight of a second polymer, which first and second polymers are not in close proximity in the triboelectric series.

Developer compositions with suspension polymerized styrene butadiene

An electrophotographic imaging process which comprises the formation of a latent image on a photoconductive imaging member; thereafter developing the image with a toner composition comprised of resin particles, pigment particles, and a sulfur containing organopolysiloxane wax; subsequently transferring the developed image to a suitable substrate; and permanently affixing the image thereto, wherein there result images with an absence of unwanted toner spots thereon.

Imaging process with prevention of toner spots

A toner composition comprised of resin particles, pigment particles, and a sulfur containing organopolysiloxane wax, such as those with

Toner and developer compositions with sulfur cotaining

Toner compositions comprised of resin particles, pigment particles, and as a charge enhancing additive inner salts wherein the negative charge center is covalently attached to the positive charge center. Also disclosed are developer compositions comprised of the aforementioned toner components and carrier particles, which compositions are particularly useful for the development of the electrostatic latent images. Additionally, there can be selected for the toner and developer compositions mixtures of charge enhancing additives including mixtures of the aforementioned inner salts and second charge enhancing additives such as quaternary ammonium compounds.
