Title (EN) TONER FOR ELECTROSTATIC CHARGE IMAGE DEVELOPMENT
(FR) TONER POUR DÉVELOPPEMENT D’IMAGE À CHARGE ÉLECTROSTATIQUE
(JA) 静電荷像現像用トナー
Abstract:
(EN) This invention provides a toner for an electrostatic charge image development, characterized by comprising a novel carbon black having a number average particle diameter of Feret's diameters of 5 to 300 nm and containing not less than 5%, on the basis of number of particles, of primary particles. The toner can prevent a change in Q/M caused by adherence onto a carrier or a sleeve, is free from fogging, toner scattering and the like, and can maintain stable performance for a long period of time.
(FR) La présente invention concerne un toner pour le développement d’image à charge électrostatique, caractérisé en ce qu’il comprend un noir de carbone innovant dont le diamètre de particule moyen de diamètres de Féret est compris entre 5 et 300 nm et ne contient pas moins de 5%, sur la base du nombre de particules, de particules primaires. Ce toner peut empêcher un changement dans le Q/M causé par l’adhérence à un porteur ou à un manchon, n’est pas sujet au voilage ou à la diffusion du toner, et autres désagréments, et peut conserver des caractéristiques stables sur une longue période de temps.
(JA)  本発明は、フェレ径の個数平均粒径が5~300nmであり、かつ一次粒子を個数基準で5%以上有する新規なカーボンブラックを含有することを特徴とする静電荷像現像用トナーに関する。  本発明のトナーは、キャリアやスリーブへの付着によるQ/Mの変化を防止でき、またカブリ、トナー飛散などがなく、長期的に安定した性能を維持できる。
