(FR) TONER ET REVELATEUR, CONTENANT POUR TONER, CARTOUCHE DE TRAITEMENT, APPAREIL DE FORMATION D'IMAGE, ET PROCEDE DE FORMATION D'IMAGE COMPRENANT L'UTILISATION DE CEUX-CI
Abstract: front page image
(EN)It is an object of the present invention to provide a toner containing an ethyl acetate-soluble polyester component and an ethyl acetate-insoluble polyester component, wherein the toner is granulated in an aqueous medium, the ethyl acetate-insoluble polyester component is obtained by elongating and/or cross-linking a modified polyester resin during granulating and/or after granulating, the modified polyester resin is produced by condensation polymerization of an acid component and at least one type of diol compound selected from aliphatic diol and alicyclic diol in the presence of a catalyst, and the mass average molecular weight of the modified polyester resin is 10,000 to 100,000.
(FR)Cette invention a pour objet un toner contenant un composant polyester soluble à l'éthyle acétate, et un composant polyester insoluble à l'éthyle acétate, ce toner se présentant sous forme granulée dans un milieu aqueux. Le composant polyester insoluble à l'éthyle acétate est obtenu par allongement et/ou réticulation d'une résine polyester modifiée au cours de la granulation et/ou après cette dernière, la résine polyester modifiée est produite par polycondensation d'un composant acide et d'au moins un type de composant diol choisi parmi les diol aliphatiques et les diols acycliques, en présence d'un catalyseur, et la masse molaire moyenne en masse de la résine de polyester modifiée est comprise entre 10 000 et 100 000.
