Abstract
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.
Claims6
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.
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.
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.
