Title (EN) POLYESTER RESIN COMPOSITION FOR ELECTROPHOTOGRAPHIC TONER, AND ELECTROPHOTOGRAPHIC TONER
(FR) COMPOSITION DE RÉSINE POLYESTER POUR TONER ÉLECTROPHOTOGRAPHIQUE, ET TONER ÉLECTROPHOTOGRAPHIQUE
(JA) 電子写真トナー用ポリエステル樹脂組成物及び電子写真トナー
Abstract:
(EN) Provided are: a polyester resin composition that can provide an electrophotographic toner having a large charge ratio and excellent electrification stability, low-temperature fixability, and offset resistance; and an electrophotographic toner including said composition. More specifically, the invention provides: a polyester resin composition for an electrophotographic toner, the composition comprising a polyester resin (A) obtained by reacting a monobasic acid (a1), a polybasic acid (a2), a polyol (a3), a monoepoxy compound (a4), and a polyepoxy compound (a5) including four or more epoxy groups; and an electrophotographic toner comprising said polyester resin composition.
(FR) L'invention fournit une composition de résine polyester permettant d'obtenir un toner électrophotographique excellent en termes de quantité de charge électrostatique, de stabilité de charge électrostatique, de propriétés de fixation à basse température et de résistance au maculage, et fournit aussi un toner électrophotographique comprenant cette composition. Concrètement, l'invention fournit une composition de résine polyester pour toner électrophotographique qui est caractéristique en ce qu'elle comprend une résine polyester (A) obtenue par réaction avec un acide monobasique (a1), un acide polybasique (a2), un alcool polyvalent (a3), un composé monoépoxy (a4), et un composé polyépoxy (a5) possédant quatre groupes époxy ou plus. En outre, l'invention fournit un toner électrophotographique qui comprend cette composition de résine polyester pour toner électrophotographique.
(JA)  帯電量、帯電安定性、低温定着性並びに耐オフセット性に優れる電子写真トナーを得ることができるポリエステル樹脂組成物、及びこれを含有する電子写真トナーを提供する。具体的には、一塩基酸(a1)、多塩基酸(a2)、多価アルコール(a3)、モノエポキシ化合物(a4)、及び4個以上のエポキシ基を有するポリエポキシ化合物(a5)と、を反応して得られるポリエステル樹脂(A)を含有することを特徴とする電子写真トナー用ポリエステル樹脂組成物、該電子写真トナー用ポリエステル樹脂組成物を含有する電子写真トナーを提供する。
