    • A fixing device has a heating rotary (30) with a nonconductive surface that contacts a press (33) to form a nip (N). A sheet passes through the nip (N) to fix a toner image on the sheet. An electrically conductive base (50) is positioned near the heating rotary. A separator (51) has a separating portion (67) for separating the sheet from the surface of the heating rotary. The separating portion faces the surface of the heating rotary at a first clearance (G1). A charge-remover (52) is retained by the base (50) for removing electric charge from the surface of the heating rotary. The charge-remover (52) has a charge-removing portion arranged along the circumferential surface of the heating rotary downstream along a rotational direction of the heating rotary (30) than the separating portion (67), and faces the surface of the heating rotary at a second clearance (G2).
    • 定影装置具有加热旋转体(30),其具有与压力机(33)接触以形成压区(N)的非导电表面。 片材通过辊隙(N)以将调色剂图像定影在片材上。 导电基座(50)位于加热旋转体附近。 分离器(51)具有用于将片材与加热旋转体的表面分离的分离部分(67)。 分离部分以第一间隙(G 1)面向加热旋转体的表面。 电荷去除器(52)由基座(50)保持,用于从加热旋转体的表面去除电荷。 电荷去除器(52)具有沿着加热旋转体的下游侧的周面配置的除电部,沿着加热旋转体(30)的旋转方向比分离部(67)高,并且面对加热旋转体 在第二间隙(G 2)处。

    • A fixing device includes a fixing rotator unit and an induction heating portion. The fixing rotator unit includes a heating rotary belt, a pressing member being in contact with the inner surface of the heating rotary belt, a pressurizing rotator forming a fixing nip between the pressurizing rotator and the pressing member, a belt guide member including a guide portion and an extending portion, positioning the heating rotary belt, and guiding rotation. The induction heating portion includes a magnetic-flux generating portion, a magnetic core portion, and a support member supporting the magnetic-flux generating portion. The support member includes a positioning portion that positions the belt guide member by coming into contact with or engaging the extending portion to control a distance between the magnetic-flux generating portion and the outer surface of the heating rotary belt.
    • 定影装置包括固定旋转单元和感应加热部分。 固定旋转单元包括加热旋转带,与加热旋转带的内表面接触的加压构件,在加压旋转体和加压构件之间形成定影夹持部的加压旋转体,包括引导部 和延伸部分,定位加热旋转带,并引导旋转。 感应加热部分包括磁通量产生部分,磁芯部分和支撑磁通量产生部分的支撑部件。 支撑构件包括定位部,其通过与延伸部接触或接合延伸部来定位带引导构件,以控制磁通量产生部和加热旋转带的外表面之间的距离。
