Claim 2
Dependent Claim
37 words
A toner composition comprising resin particles, pigment particles, and a wax component, characterised in that the wax component comprises a polymeric alcohol of the formula CH₃(CH₂) n CH₂OH wherein n is from about 30 to about 300.
Claim 3
Dependent Claim
26 words
A toner composition in accordance with claim 1 wherein the polymeric alcohol wax has a number average molecular weight of from about 475 to about 1,400.
Claim 4
Dependent Claim
22 words
A toner composition in accordance with claim 1 or claim 2 wherein the polymeric alcohol wax is present as an external component.
Claim 5
Dependent Claim
34 words
A toner composition in accordance with any one of claims 1 to 3 wherein the wax is present in an amount of from about 0.05 percent by weight to about 20 percent by weight.
Claim 6
Dependent Claim
35 words
A toner composition in accordance with any one of claims 1 to 4 wherein the resin particles are selected from the group consisting of polyesters, styrene butadiene copolymers, styrene acrylate copolymers, and styrene methacrylate copolymers.
Claim 7
Dependent Claim
38 words
A toner composition in accordance with claim 5 wherein the polyester results from the condensation reaction of dimethylterephthalate, 1,2-propanediol, 1,3-butanediol, and pentaerythritol; or wherein the polyester results from the condensation reaction of dimethylterephthalate, 1,2-propanediol, diethylene glycol, and pentaerythritol.
Claim 8
Dependent Claim
36 words
A toner composition in accordance with any one of claims 1 to 6 further including therein a charge enhancing additive selected from distearyl dimethyl ammonium methyl sulfate, cetyl pyridinium halides, and stearyl phenethyl dimethyl ammonium tosylate.
Claim 9
Dependent Claim
18 words
A developer composition comprising the toner composition of any one of claims 1 to 7, and carrier particles.
Claim 10
Dependent Claim
51 words
A developer composition in accordance with claim 8 wherein the carrier particles are comprised of a steel or a ferrite core with a coating thereover selected from the group consisting of polychlorotrifluoroethylene-co-vinylchloride copolymer, a polyvinylidene fluoropolymer, or a terpolymer of styrene, methacrylate, and an organo silane, fluorinated ethylene-propylene copolymers, and polytetrafluoroethylene.
Claim 11
Independent Claim
52 words
A method for obtaining images which comprises generating an electrostatic latent image on a photoconductive imaging member, subsequently effecting development of this image with the toner or developer composition of any one of claims 1 to 9, thereafter transferring the image to a permanent substrate, and optionally permanently affixing the image thereto.
