摘要： A conveying device includes: a rotating roll; a conveying belt that rotates, nipping a conveyed member between the conveying belt and the rotating roll; and a pressing member that is disposed at the inner periphery of the conveying belt and pressing the conveying belt towards the rotating roll. The pressing member includes an opposing face formed with a pressure point where the pressing force of the conveying belt towards the rotating roll is greatest, and an inclined face that is formed at the belt rotation direction upstream side relative to the pressure point. The inclined face inclines at an angle relative to a parallel line such that the inclined face separates away from the rotating roll, and the parallel line being parallel to a tangent to the rotating roll outer peripheral surface and passing through the pressure point.

摘要： A conveying path switching structure includes a cover unit and a conveying path switch unit. The cover unit is attached to an image forming apparatus main body so as to be movable between a close state and an open state in which a fixing unit is exposed. The conveying path switch unit is rotatably attached to the cover unit and that switches a conveying path of a record medium between a discharge conveying path and a double-side conveying path. The discharge conveying path is a path where the record medium is conveyed from a discharge part of the fixing unit to a discharge unit that discharges the record medium to outside of the image forming apparatus main body in a close state. The double-side conveying path is a path where the record medium is conveyed again to an image forming unit.

摘要： A fixing unit includes a heating roll, an endless belt and a pressing body having a hard pressing member and a soft pressing member. The hard pressing member is placed on a downstream of a passage direction of a record medium in a press contact part and forms higher hardness than an elastic layer of the heating roll. The soft pressing member is placed on an upstream of the passage direction from the hard pressing member, and forms lower hardness than the elastic layer. The press contact part is formed in a state in which a first press contact portion of the hard pressing member is longer than a second press contact portion of the soft pressing member. The hard pressing member has an end part opposed to the heating roll on the upstream. The end part has a face approaching the heating roll from the upstream to the downstream.
