A fixing device is provided with a fixing device body, a fixing member, and a first attachment section. The fixing device body is adapted to attach to and detach from an apparatus body of a double-sided image forming apparatus, which has a return passage through which a recording medium is returned to an image forming position, and an apparatus body of a single-sided image forming apparatus, which does not have the return passage. The first attachment section is provided at a return passage side in the fixing device body, and is adapted to have a passage surface member, which has a passage surface of an introduction passage through which a fixed recording medium is introduced into the return passage, attached thereto.

Fixing device, single-sided image forming apparatus, and double-sided image forming apparatus

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.

Conveying path switching structure and image forming apparatus

A fixing device includes a main body mounted on an image forming apparatus body; a fixing member that is included in the main body and that fixes an image to a recording medium; a pair of conveying rolls that is supported by the main body and that conveys the recording medium to which an image is fixed by the fixing member, the pair of conveying rolls comprising a driven roll and a driving roll disposed under the driven roll; and an exterior portion that is formed in the main body, disposed under the driving roll, forms an exterior face of the main body, and also forms an exterior face of the image forming apparatus body while the main body is mounted on the image forming apparatus body.

Fixing device and image forming apparatus

A fixing device comprises: a pair of fixing rotors, at least one of which has a heating source and both of which are rotated in pressure contact with each other; and a click-shaped peeling member provided on a downstream side of the fixing rotor with respect to a transporting direction of a recording medium and disposed in contact with a surface of the fixing rotor, wherein a tip portion of the click-shaped peeling member which is to come in contact with the fixing rotor is elastically deformed in conformity to a shape of a surface of the fixing rotor when coming in contact with the fixing rotor.

A conveying device includes: a rotating body that rotates; a belt that contacts the rotating body and rotates; a restricting member that is disposed at each of the two rotation axis direction side edges of the belt, positions the side edges of the belt, and restricts movement of the belt in the rotation axis direction; a lubrication agent that is supplied to the inner peripheral face of the belt; and a slide bearing that is disposed so as to overlap in the rotation axis direction with the restricting member when viewed along a rotating body radial direction, the slide bearing being open to the belt side and rotatably supporting the rotating body.

Conveying device, fixing device and image forming apparatus

A fixing device comprises a heating roll; an endless belt; and a pressurizing member that forms a pressure contact portion for pushing the endless belt against an outer peripheral surface part of the heating roll from an inner peripheral surface side of the pressurizing member so that a recording medium holding an unfixed image passes between the pressure contact portion and the heating roll, wherein the pressurizing member includes: a hard pressurizing member and a soft pressurizing member the hard pressurizing member, and the soft pressurizing member are disposed in a state in which a clearance is present between the hard pressurizing member and the soft pressurizing member in a specific region part so that at least a specific recording medium passes in a fixing region of the pressure contact portion in the rotating axis direction of the heating roll.
