摘要： A fixing device includes a fixing belt that is endless and rotatable in a rotation direction and a nip former stretching the fixing belt and including an elastic layer as a surface layer. A pressure rotator presses against the nip former via the fixing belt to form a fixing nip between the fixing belt and the pressure rotator, through which a recording medium is conveyed. A presser is disposed downstream from an exit of the fixing nip in a recording medium conveyance direction. The presser brings the fixing belt into contact with the pressure rotator.

摘要： The fixing device includes first and second heat sources, a rotatable fixing member heated by the first heat source, a rotatable pressing member heated by the second heat source and contacting the fixing member to form a fixing nip therebetween at which a toner image on a sheet is fixed thereto, and at least first and second temperature detectors determining temperatures of different surface portions of the pressing member. The pressing member has a width greater than that of the fixing member greater than the maximum width of the sheet accommodated by the fixing device. The first temperature detector determines the temperature of a surface portion of the pressing member, which is to be contacted with the sheet, and the second temperature detector determines the temperature of a second surface portion of the pressing member, which is not contacted with the fixing member even when the pressing member is rotated.

摘要： A pressing device includes a pressure lever that is platy and has a thickness t. The pressure lever pivots. A cam presses the pressure lever. A cam follower is mounted on the pressure lever and disposed opposite the cam. The cam follower transmits pressure from the cam to the pressure lever. The cam follower has a contact face that contacts the cam and a side face that is perpendicular to the contact face. The contact face has a length W in a thickness direction of the pressure lever and a length L1 in an orthogonal direction perpendicular to the thickness direction of the pressure lever. The length L1 is defined from a contact position where the cam follower contacts the cam to the side face of the cam follower. The thickness t, the length W, and the length L1 satisfy a relation defined by L1≥0.6×(W−t)/2+0.2.

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, and a guide. The pressing rotator forms a fixing nip with the fixing rotator. The guide guides a recording medium to the fixing nip. The guide includes a guide surface that contacts a surface of the recording medium against a guide the recording medium. The guide surface is provided parallel to a line tangent to the fixing rotator and the pressing rotator.

摘要： A sheet separation device includes a separator disposed to contact one face of a sheet conveyed through a nip between conveyors contacting each other. The separator configured to separate from surfaces of the conveyors the sheet conveyed through the nip. The separator includes a conveyance face and a slanted face. The conveyance face is configured to contact and convey the sheet conveyed through the nip. The slanted face is disposed closer to the nip than the conveyance face and inclined with respect to the conveyance face toward one conveyor of the conveyors at a same side as the one face of the sheet.
