Abstract
A method of imaging which comprises formulating an electrostatic latent image on an imaging member, affecting development thereof with a toner composition comprised of resin particles, and pigment particles, and which composition includes thereon a surface additive mixture of silica, or titanium dioxide, metal salts of fatty acids, and an aluminum complex, and thereafter transferring the developed image to a suitable substrate.
Claims24
A method for avoiding toner impaction onto development wires present in a xerographic imaging method consisting essentially of providing a xerographic imaging apparatus containing an imaging member, formulating an electrostatic latent image on said imaging member, affecting development thereof with a developer consisting essentially of carrier particles and a toner composition consisting essentially of resin particles, and pigment particles, and which composition includes thereon a surface additive mixture of silica or titanium dioxide, metal salts of fatty acids, and an aluminum complex, and thereafter transferring the developed image to a suitable substrate with said development wires, and wherein each of said silica or titanium dioxide, said metal salts of fatty acids, and said aluminum complex are present in an amount of from about 0.01 to about 2 weight percent, and wherein said aluminum complex is tris (3,5-di-tertiary-butyl salicylato) aluminum.
A method for avoiding toner impaction onto development wires present in a xerographic imaging apparatus consisting of providing a xerographic imaging apparatus containing development wires therein, formulating an electrostatic latent image on a layered photoconductive imaging member, affecting development thereof with a developer consisting of carrier particles and a colored toner composition comprised of resin particles and pigment particles of cyan, magenta, yellow, or mixtures thereof, and which composition includes thereon a surface additive mixture of silica, metal salts of fatty acids, and an aluminum complex, transferring the developed image to a suitable substrate with said development wires, and fixing the image thereto, and wherein each of said silica metal salts of fatty acid and aluminum complex are present in an amount of from 0.01 to about 2 weight percent, wherein said aluminum complex is tris (3,5-di-tertiary-butylsalicylato) aluminum, and said toner possesses a narrow A.sub.t of from about 60 to about 95.
A method for avoiding toner impaction onto development wires present in a xerographic imaging apparatus consisting of providing a xerographic imaging apparatus containing development wires therein, formulating an electrostatic latent image on a layered photoconductive imaging member, affecting development thereof with a developer consisting of carrier particles and a toner composition comprised of resin particles and pigment particles of cyan, magenta, yellow, or mixtures thereof, and which composition includes thereon a surface additive mixture of titanium dioxide, metal salts of fatty acids, and an aluminum complex, transferring the developed image to a suitable substrate with said development wires, and fixing the image thereto, and wherein each of said silica, said metal salts of fatty acid and said aluminum complex are present in an amount of 0.4 weight percent and 0. 1 weight percent for said aluminum complex, wherein said aluminum complex is tris (3,5-di-tertiary-butylsalicylato) aluminum, and said toner possesses a narrow A.sub.t of from about 60 to about 95.
A process for minimizing or avoiding contamination of development wires utilized for transfer in a xerogrephic imaging method, which process consists of providing a photoconductive imaging member with a charge transport layer and a photogenerating layer, generating an electrostatic latent image on the imaging member, effecting development thereof with a developer, composition consisting essentially of carrier and a toner composition containing resin particles and pigment particles, and which cornposition includes on the surface thereof silica or titanium dioxide, zinc stearate, and an aluminum complex, and wherein the aluminum complex is tris (3,5-di-tertiary-butylsalioylato) aluminum, thereafter transferring the developed image to a suitable substrate, the improvement residing in selecting said silica, or said titanium dioxide, said zinc stearate, and said aluminum complex in an amount of from about 0.01 to about 2 weight percent, and wherein said development effects such transfer and wherein said development wires are free of toner contamination.
