Abstract:
(EN) The present invention comprises a fixing device 200 that has a heater 300 capable of selectively heating a plurality of heat-generation blocks distributed along the longitudinal direction of a substrate 305, and is characterised by comprising an electric current control unit 400 that obtains the cumulative amounts of heat generated in a plurality of heat-generation areas, the cumulative rotation time of a pressurising roller 208, and information about a recording material which passes through a fixing nip part, and, on the basis of the information obtained, controls the electric current of heat-generation bodies 302a, 302b.
(FR) La présente invention comprend un dispositif de fixation (200) comprenant un dispositif de chauffage (300) apte à chauffer sélectivement une pluralité de blocs de génération de chaleur distribués le long de la direction longitudinale d'un substrat (305), et est caractérisé en ce qu'il comprend une unité de commande de courant électrique (400) qui obtient les quantités cumulatives de chaleur générées dans une pluralité de zones de génération de chaleur, le temps de rotation cumulatif d'un rouleau de pressurisation (208), et des informations concernant un matériau d'enregistrement qui passe à travers une partie de pincement de fixation, et, sur la base des informations obtenues, commande le courant électrique des corps de génération de chaleur (302a, 302b).
(JA) 基板305の長手方向に分割された複数の発熱ブロックを選択的に発熱可能なヒータ300を有する定着装置200において、通電制御部400は、定着動作を行った際における、複数の加熱領域のそれぞれにおける累積発熱量と、加圧ローラ208の累積回転時間と、定着ニップ部を通過する記録材の情報と、を取得し、取得した情報に基づいて、発熱体302a、302bの通電を制御することを特徴とする。
