Claims

[Scope of Claim for Utility Model Registration] (1) In a fixing device of an electrostatic recording device that performs wet development, the unfixed toner image bearing surface of the transfer paper is sandwiched between the paper passage path of the transfer paper carrying the unfixed toner image. A metal fixing roller having an internal heat source is provided on the back side of the transfer paper, and a plurality of pressing rollers are provided on the unfixed toner image bearing surface of the transfer paper to bring the transfer paper into close contact with the fixing roller. A fixing device comprising a means for applying a release oil to the surface of the fixing device. (2) The fixing device according to claim 1, wherein the fixing roller has fine irregularities on its surface in the axial direction. (3) In the fixing device of an electrostatic recording device that performs wet development, an internal heat source is installed on the back side of the unfixed toner image-bearing surface of the transfer paper, sandwiching the paper path of the transfer paper that carries the unfixed toner image. A plurality of pressing rollers are provided on the unfixed toner image bearing surface of the transfer paper to bring the transfer paper into close contact with the fixing roller, and a layer of oil repellent is applied to the surface of the pressing roller. A fixing device characterized in that: (4) The fixing device according to claim 3, wherein the pressing roller has fine irregularities on its surface.
