    • A fixing device includes a fixing rotator, a pressing rotator, an oil applicator, a first adjuster, a surface modifier, a second adjuster, and a processor. The fixing rotator contacts a recording medium bearing a toner image. The pressing rotator forms a fixing nip with the fixing rotator. The oil applicator is pressed against at least one of applied members of the fixing rotator and pressing rotator. The first adjuster adjusts contact/separation of the oil applicator with respect to the applied member. The surface modifier contacts the fixing rotator to modify a surface thereof. The second adjuster adjusts contact/separation of the surface modifier with respect to the fixing rotator. The processor allows the surface modifier to modify the fixing rotator surface after the oil applicator contacts the applied member, and the oil applicator to separate from the applied member after the surface modifier is separated from the fixing rotator.
    • 定影装置包括固定旋转器,按压旋转器,油涂布器,第一调节器,表面改性剂,第二调节器和处理器。 定影旋转器接触带有调色剂图像的记录介质。 按压旋转体与定影旋转体形成定影辊隙。 油涂敷器被压在固定旋转器和按压旋转器的施加部件中的至少一个上。 第一调节器调节涂油器相对于所施加的构件的接触/分离。 表面改性剂接触固定旋转体以改变其表面。 第二调节器调节表面改性剂相对于固定旋转器的接触/分离。 处理器允许表面改性剂在涂油器接触所施加的构件之后修改固定旋转体表面,并且在表面改性剂与固定旋转体分离之后,油涂布器与施加的构件分离。

    • A fixing device includes a first rotator rotatable in a given direction of rotation and a second rotator contacting the first rotator to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed. A heater is disposed opposite and heats at least one of the first rotator and the second rotator. An abutment separably contacts the first rotator to refresh an outer circumferential surface of the first rotator. A mover is connected to the abutment to move the abutment with respect to the first rotator. A degradation estimator is operatively connected to the mover to estimate a degradation level of the outer circumferential surface of the first rotator and control the mover to move the abutment with respect to the first rotator according to the degradation level of the first rotator.
    • 定影装置包括可沿给定旋转方向旋转的第一旋转器和与第一旋转器接触的第二旋转器,以在其间输送承载调色剂图像的记录介质。 加热器相对设置并加热第一旋转器和第二旋转器中的至少一个。 基座可分离地接触第一旋转器以刷新第一旋转器的外周表面。 移动器连接到支座以相对于第一旋转器移动支座。 降级估计器可操作地连接到移动器以估计第一旋转器的外圆周表面的劣化水平,并且根据第一旋转器的劣化水平控制移动器相对于第一旋转器移动邻接件。

    • A separation device separates a recording medium ejected from a fixing nip formed between a first rotator and a second rotator from the first rotator. The separation device includes a separator including a front end disposed opposite the fixing nip and the recording medium and a plurality of recesses disposed on the front end of the separator at least in a conveyance span on the separator where the recording medium is conveyed. The plurality of recesses includes a first recess extending in a first extension line that is oblique relative to a recording medium conveyance direction and a second recess adjacent to the first recess and extending in a second extension line that is oblique relative to the recording medium conveyance direction. The second extension line overlaps the first extension line in a direction perpendicular to the recording medium conveyance direction to define an overlap span.
    • 分离装置将形成在第一旋转体和第二旋转体之间的定影辊隙排出的记录介质从第一旋转体分离。 分离装置包括分离器,其包括与定影辊隙和记录介质相对设置的前端,以及至少在传送跨越记录介质的分离器上的输送跨度中的多个凹槽。 所述多个凹部包括在相对于记录介质传送方向倾斜的第一延伸线中延伸的第一凹部和与所述第一凹部相邻的第二凹部,并且在相对于所述记录介质传送方向倾斜的第二延长线中延伸 。 第二延伸线在垂直于记录介质输送方向的方向上与第一延伸线重叠以限定重叠跨度。

    • An image forming apparatus includes a rotary fixing member cleaner that includes a freely rotatable rotary unwinding member, around which a cleaning web winds, a rotary winding member to wind the cleaning web thereon from one end thereof, and a load applicator to apply a load to the cleaning web unwound from the rotary unwinding member. The rotary fixing member cleaner removes any unnecessary substance adhering to an outer circumferential surface of the rotary fixing member therefrom by unwinding and moving the cleaning web from the rotary unwinding member in an opposite direction to a direction of movement of the outer circumferential surface of the rotary fixing member at a contacting point at which the cleaning web contacts the outer circumferential surface of the rotary fixing member. The load applicator presses against the cleaning web winding around the rotary unwinding member at a prescribed angular contact position.
