    摘要: A separation device includes a separator that separates a recording medium from a rotator and a plurality of recesses disposed on a conveyance path side face of the separator over which the recording medium is conveyed in a recess span in a recording medium conveyance direction and at least in a conveyance span 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 the recording medium conveyance direction and a second recess being adjacent to the first recess in a direction perpendicular to the recording medium conveyance direction. The second recess extends in a second extension line that is oblique relative to the recording medium conveyance direction and overlaps the first extension line of the first recess in the direction perpendicular to the recording medium conveyance direction to define an overlap span.

    摘要: 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.

    摘要: 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.
