Title
(EN) FIXING DEVICE AND IMAGE-FORMING APPARATUS
(FR) DISPOSITIF DE FIXATION ET APPAREIL DE FORMATION D'IMAGE
(JA) 定着装置及び画像形成装置
Abstract
(EN)
A fixing device comprising: a heating unit that provides non-contact heating of a surface of a recording medium; a transport unit that faces the surface towards the heating unit and transports the recording medium; and a maintenance unit that maintains the non-contact state such that a rear surface, being the opposite side to the surface and being inside an image area in which an unfixed image is formed on the surface, is in a non-contact state and the recording medium is transported in said state by the transport unit.
(FR)
Un dispositif de fixation comprend : une unité de chauffage qui assure un chauffage sans contact d'une surface d'un support d'enregistrement; une unité de transport qui fait face à la surface vers l'unité de chauffage et transporte le support d'enregistrement; et une unité de maintenance qui maintient l'état sans contact de telle sorte qu'une surface arrière, étant le côté opposé à la surface et étant à l'intérieur d'une zone d'image dans laquelle une image non fixe est formée sur la surface, se trouve dans un état sans contact et le support d'enregistrement est transporté dans ledit état par l'unité de transport.
(JA)
定着装置は、記録媒体の表面を非接触で加熱する加熱部と、前記加熱部に前記表面を対向させながら前記記録媒体を搬送する搬送部と、前記表面とは反対側の裏面であって、前記表面に未定着画像が形成される画像領域内の前記裏面が非接触状態で前記搬送部によって前記記録媒体が搬送されるように、当該非接触状態を維持する維持部と、を備える。
