Abstract: front page image
(EN)This invention provides a method for image formation in which an unfixed toner image is fixed in a noncontact manner by high frequency magnetic induction heating. In this method, a toner containing a binder resin and superparamagnetic fine particles with a diameter of 100 nm or less is used. According to this constitution, scattering of the toner caused by the influence of a magnetic field can be prevented, and a high quality image can be formed.
(FR)La présente invention concerne un procédé de formation d'image, dans lequel une image toner non fixée est fixée sans contact par un chauffage par induction magnétique haute fréquence. Dans ce procédé, on utilise un toner contenant une résine liante et des particules fines superparamagnétiques ayant un diamètre de 100 nm ou moins. Avec cette configuration, on peut éviter une dispersion du toner due à l'influence d'un champ magnétique, et on peut former une image de haute qualité.
(JA) 未定着トナー像を高周波磁気誘導加熱により非接触で定着する画像形成方法において、トナーとして、結着樹脂と粒子径が100nm以下の超常磁性微粒子を含むものを使用することにより、磁界の影響によるトナーの飛散を防ぎ、高画質の画像を形成する。
