    Abstract: A sheet conveyance unit includes a sheet inlet port, an inlet guide, and a guide switching mechanism. The inlet guide has an upper guide and a lower guide below the upper guide. The guide switching mechanism switches a position of the inlet guide between a conveyance position at which the upper guide and the lower guide face each other with a first distance and a separation position at which the upper guide and the lower guide are spaced from each other by a second distance greater than the first distance. To connect the sheet conveyance unit to the sheet discharge unit, the inlet guide is disposed to the separation position before the discharge guide is inserted between the upper guide and the lower guide, and is disposed to the conveyance position after the discharge guide is inserted between the upper guide and the lower guide.

    Abstract: A fixing device includes a fixing member, a separation member, a movement mechanism, and a pressing member. The fixing member rotates around a rotation axis extended in a rotation axis direction and fixes a toner image on a recording medium. The separation member comes in contact with the fixing member and separates the recording medium from the fixing member. The movement mechanism moves the separation member in the rotation axis direction and within a movement area. The pressing member presses the separation member against the fixing member. A pressing load of the separation member against the fixing member in a case where the separation member is located at a central position of the movement area is lower than a pressing load of the separation member against the fixing member in a case where the separation member is located at both end positions of the movement area.

    Abstract: A sheet conveyance device 10 includes a first conveyance path 12a having a linear portion 121 along which a sheet is to be linearly conveyed, a second conveyance path 12b branched from the linear portion 121 and a branch member 30 which is to be set selectively to a first position for guiding the sheet to a downstream side of the first conveyance path 12a or a second position for guiding the sheet to the second conveyance path 12b. The branch member 30 is made up of a resinous guide body 31 having a first guide surface 31a for guiding the sheet to a downstream side of the first conveyance path 12a, and a metallic guide plate 35. A second guide surface 35a for guiding the sheet to the second conveyance path 12b is formed of the resinous guide body 31 and the metallic guide plate 35.

    Abstract: A fixing device includes a pressing roller, a rotating member, a heating means, a pressing mechanism, a separation member, a first biasing member and a moving mechanism. The pressing roller has a core metal and an elastic layer. The separation member includes a contact part. The first biasing member is configured to bias the separation member to be rotated in a direction in which the contact part is butted against the rotating member. The first biasing member includes a first end portion by which biasing force is acted on the separation member and a second end portion opposite to the first end portion. The moving mechanism is configured to move the second end portion of the first biasing member in a direction in which the biasing force is decreased, as the core metal approaches the rotating member owing to decrease in rigidity of the elastic layer of the pressing roller.

    Abstract: A sheet conveying device includes a correcting unit. The correcting unit corrects displacement of a sheet conveyed from an upstream side conveying path, and conveys the sheet to a downstream side conveying path. The correcting unit includes a first conveying part conveying the sheet, a first moving part moving a first frame supporting the first conveying part and a detecting part detecting a side end edge of the sheet at a reference position without displacement. The first conveying part stops conveyance of the sheet when a leading end of the sheet reaches the detecting part. While the driving of the first conveying part is stopped, the first moving part moves the first frame to move the sheet, and stops movement of the first frame, when detection result of the detecting part is changed, to position the side end edge to the reference position to correct displacement of the sheet.
