摘要:
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.
摘要:
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.
