Title
(EN) TONER, METHOD FOR PRODUCING THE SAME, IMAGE FORMATION METHOD AND IMAGE FORMATION APPARATUS
(FR) TONER ET SON PROCEDE DE FORMATION, ET PROCEDE ET APPAREIL DE FORMATION D'IMAGE
Abstract
(EN) There is provided a toner having favourable development characteristics and favourable stability and a method for production thereof. The toner comprises at least a graft copolymer and a coloring material, wherein the graft copolymer is formed by graft polymerization of a polymerizable monomer with a block copolymer having a polymerizable functional group on a side chain. The method for producing the toner has a step of subjecting a reaction mixture comprising at least a block copolymer having a polymerizable functional group in a side chain and having a polyalkenyl ether repeating unit structure, a polymerizable monomer, and a coloring material to suspension polymerization or emulsion polymerization, to produce a graft copolymer in which a polymer of the polymerizable monomer is grafted to the side chain of the block copolymer.
(FR) L'invention concerne un toner à caractéristiques de développement et à stabilité avantageuses, et son procédé de production. Ledit toner comprend au moins un copolymère greffé et une matière de coloration, ledit copolymère greffé étant formé par polymérisation avec greffage d'un monomère polymérisable avec un copolymère séquencé comprenant un groupe fonctionnel polymérisable sur une chaîne latérale. Le procédé de production du toner consiste à soumettre un mélange de réaction, comprenant au moins un copolymère séquencé doté d'un groupe fonctionnel polymérisable sur une chaîne latérale, une structure d'unité de répétition d'éther polyalcényle, un monomère polymérisable et une matière de coloration, à une polymérisation en suspension ou en émulsion afin de produire un copolymère greffé dans lequel un polymère du monomère polymérisable est greffé sur la chaîne latérale copolymère séquencé.
