Toner, developer, and method of manufacturing toner
In the present invention, provided is a toner suitable for fixing at low temperature, which exhibits excellent performance against thermal stress as well as mechanical stress with no generation of blocking even during storage for a long duration in an unused state, and also with no generation of tacking of toner images after fixing. Also disclosed is a toner comprising at least a binder resin, a colorant and a wax, the toner comprising a fatty acid ester wax comprising a hydroxyl group, and an aliphatic alcohol.
1. A toner comprising at least a binder resin, a colorant, an aliphatic alcohol,
and a fatty acid ester wax having a hydroxyl group,
wherein the fatty acid ester wax is a dehydrating condensation reactant made from an aliphatic alcohol and one selected from a citric acid, a dihydroxysuccinic acid and a malic acid.
2. The toner of claim 1 ,
wherein the aliphatic alcohol has 10-40 carbon atoms.
3. The toner of claim 1 ,
wherein the aliphatic alcohol is contained in an amount of 3-80 mol %, based on the fatty acid ester wax having a hydroxyl group.
4. A developer comprising the toner of claim 1 .
5. A method of manufacturing a toner comprising a binder resin, a colorant, and a wax, comprising the steps of:
polymerizing polymerizable monomers comprising an aliphatic alcohol and a fatty acid ester wax comprising a hydroxyl group which is a dehydrating condensation reactant made from an aliphatic alcohol and one selected from a critric acid, a dihydroxysuccinic acid and a malic acid to form resin particles constituting the binder resin, and
coagulating/fusing the resin particles and colorant particles to prepare the toner.
6. A method of manufacturing a toner comprising a binder resin, a colorant and a wax, comprising the step of:
coagulating/fusing resin particles constituting the binder resin having been formed via polymerization of polymerizable monomers; admixture particles formed from an aliphatic alcohol and a fatty acid ester wax comprising a hydroxyl group which is a dehydrating condensation reactant made from an aliphatic alcohol and one selected from a critric acid, a dihydroxysuccinic acid and a malic acid; and colorant particles to prepare the toner.
