Abstract | A toner having excellent coloring properties, mold-releasing properties, electrostatic properties and surface properties is disclosed whose surface is covered with a coating layer by using at least one of a supercritical fluid or a subcritical fluid. Also disclosed is a method for efficiently producing such a toner with only a little burden on the environment. Specifically, the method for producing such a toner comprises a step for forming major toner particles wherein major toner particles respectively containing at least a resin particle are formed, and a step for forming a coating layer wherein a coating layer is formed on the surface of each major toner particle by having the surface adhered by or covered with a toner functional material using at least one of a supercritical fluid or a subcritical fluid.
La présente invention a trait à une poudre imprimante présentant d'excellentes propriétés de coloration, propriétés antiadhérentes, propriétés électrostatiques et propriétés de surface dont la surface est revêtue d'une couche d'enrobage à l'aide d'au moins un fluide supercritique ou un fluide sous-critique. L'invention a également trait à un procédé pour la production efficace d'une telle poudre imprimante avec très peu d'effet nuisible sur l'environnement. De manière spécifique, le procédé pour la production d'une telle poudre imprimante comprend les étapes suivantes : la formation de particules de poudre imprimantes majoritaires, lesdites particules de poudre imprimantes majoritaires contenant respectivement au moins une particule de résine étant formées, et la formation d'une couche d'enrobage, ladite couche d'enrobage étant formée à la surface de chaque particule majoritaire de poudre imprimante en ayant une surface collée ou revêtue d'un matériau fonctionnel de poudre imprimante au moyen d'au moins un fluide supercritique ou un fluide sous-critique. |
