Provided is a fixing device including a fixing unit that includes a pipe-shaped fixing member which includes an outermost layer including at least one selected from a group consisting of a hydrogenated nitrile rubber and a denatured hydrogenated nitrile rubber, and heats and pressurizes the recording medium to fix an unfixed developer image on a recording medium by bringing the outermost layer into contact with a surface of the recording medium which holds the developer image, the recording medium being transported while holding the unfixed developer image, and a heating unit that is disposed on an upstream side of the fixing unit in a transport direction of the recording medium, and heats the recording medium transported while holding the unfixed developer image.

Fixing device and image forming apparatus

Provided is an image forming apparatus including a first image forming unit that forms a first image on a front surface of a transported medium with a developer including toners and non-volatile oils, a removing unit that heats non-volatile oils on the front surface of the medium to remove the oils, a second image forming unit that forms a second image on a back surface of the medium with a developer including toners and non-volatile oils, a removing section that heats non-volatile oils on the back surface of the medium to remove the oils, and a fixing unit that fixes the first image and the second image on the front surface and the back surface of the medium.

Image forming apparatus

Provided is a fixing device including a heating section that is arranged to be out of contact with a recording medium which is transported, and heats a developer image on the recording medium, a contact member that is arranged on a downstream side from the heating section in a transport direction of the recording medium, and is in contact with an image surface on a developer image side of the recording medium, and a folding member that is arranged between the heating section and the contact member, and folds a transport path of the recording medium from the heating section to the contact member to a side opposite to an image surface side from an extended line so that the contact member is positioned on the opposite side of the heating section from an extended line of the transport path which faces the heating section.

Fixing device, and image forming apparatus

A recording material processing apparatus includes a recording material supplying device supplying a recording material, an image recording device recording an image on the recording material, a recording material transporting mechanism and a burr curing device including a pressurizing member for curing the burrs at the edge of the recording material. The recording material transporting mechanism changes a transporting state of the recording material at a predetermined transportation changing position. The pressurizing member is provided on a recording material transporting path between the recording material supplying device and the transportation changing position and is provided on the side nearer to the recording material supplying device than a trailing end position. The trailing end position indicates a position of the trailing end of the recording material in the transporting path when a leading end of the recording material in the transporting direction passes the transportation changing position.

Recording material processing apparatus having a burr curing device

An image forming apparatus includes: a transporting path; a heating unit on the transporting path that is movably provided in a direction coming in contact with and departing from a continuous recording medium and that heats the continuous recording medium; a braking unit that has a first braking member and a second braking member and that brakes transportation of the continuous recording medium by sandwiching in the continuous recording medium between the first and second braking members, wherein the first and second braking members are provided on upstream and downstream sides on the transporting path of the heating unit, respectively; and a control unit that controls that the heating unit is brought into contact with the continuous recording medium and the braking of the continuous recording medium is released by the braking unit.

A fixing device fixes a toner image carried on a recording medium. The fixing device includes a rotatable fixing roll member, a fixing belt member and a walk adjustment mechanism. The fixing belt member is wound on the fixing roll member so as to be rotatable. The walk adjustment mechanism changes a walk width of the fixing belt member in accordance with a width of the recording medium.

Fixing device, image forming apparatus and method for controlling fixing device

A fixing unit for fixing a toner image on a recording material includes: a rotatable fixing roll; a fixing belt stretched on the fixing roll; at least one tension roll stretching the fixing belt with the fixing roll; a pressurization member disposed to give a pressure to the fixing roll; and a stripping member disposed to press the outer surface of the fixing belt onto the pressurization member in a vicinity of a downstream side of a first contact portion between the fixing roll and the pressurization member.

Fixing unit and image forming apparatus

A fixing unit that fixes a toner image carried on a recording medium includes a rotation member, and a pressure belt module that is provided with a pressure belt, a pressure roller supporting the pressure belt and pressing the rotation member, and a belt-supporting roller supporting the pressure belt. The pressure roller includes a first roller that is formed into a cylindrical shape, and a second roller that is disposed inside the first roller and formed into a crown shape, in which an axially central portion thereof is larger in outer diameter than both end portions thereof.

Fixing unit image forming apparatus with interior crown-shaped roll

An image forming apparatus includes: a transfer unit T2 including the inside transfer roll 29, the outside transfer roll 30 transfers the toner image from the toner image holding belt B onto the recording sheet that passes through the transfer region Q4 when transfer voltage is applied to between the inside transfer roll 29 and the outside transfer roll 30; electric-field adjusting conductive member 51 disposed in proximity to and along the inner side of the toner image holding belt B leaving the transfer region Q4 at a position located downstream of the transfer region Q4; and electric-field adjust-potential applying means 53; 54 applies a potential, which weakens an electric field developed between the outside transfer roll 30 and the inside transfer roll 29 in a region located downstream of the transfer region Q4, to the electric-field adjusting conductive member 51.
