    • 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 rotary fuser member, a rotary pressure member, a first media stripper, and a second media stripper. The rotary fuser member is subjected to heating. The rotary pressure member is pressed against the fuser member to form a fixing nip therebetween through which a recording medium is passed in a media conveyance direction under heat and pressure as the fuser and pressure members rotate together. The first media stripper includes at least one pneumatic nozzle disposed adjacent to the fuser member to direct compressed gas toward the fixing nip along the fuser member for stripping the recording medium from the fuser member. The second media stripper includes at least one contact finger disposed in contact with the pressure member to slide against the pressure member during rotation for stripping the recording medium from the pressure member.
    • 定影装置包括旋转定影器构件,旋转压力构件,第一介质剥离器和第二介质剥离器。 旋转定影部件经受加热。 旋转压力构件被压靠在定影构件上,以在它们之间形成定影夹持器,当定影器和压力构件一起旋转时,记录介质在介质输送方向上在加热和压力下通过。 第一介质剥离器包括至少一个与定影器构件相邻设置的气动喷嘴,以沿着定影器构件将压缩气体引向定影辊隙,用于从定影器构件剥离记录介质。 第二介质剥离器包括至少一个与压力构件接触的接触指状件,以在旋转期间抵靠压力构件滑动,以从压力构件剥离记录介质。
