Definitions
- the present invention relates to a pressure roller used in a fixing unit of an electrophotographic image forming apparatus. More specifically, the present invention relates to a fixing unit that heats and presses a torch image formed on a transfer material such as paper and fixes it on the transfer material, and is disposed opposite to the fixing roller or the fixing belt. It is related with the pressure roller.
- the toner image on the transfer material is generally fixed by various methods such as heating, pressing, and solvent vapor.
- an image forming apparatus such as an electrophotographic copying machine, heating and pressing are generally performed.
- Fixing The toner used as a developer is composed of colored resin particles containing a colorant and other additive components in a binder resin.
- the toner is roughly classified into a pulverized toner and a polymerized toner according to the manufacturing method.
- the toner is heated and pressurized at a temperature equal to or higher than the melting point or softening temperature of the binder resin, the toner is melted or softened and fused onto the transfer material.
- the fixability deteriorates because the speed of the transfer material that passes through the fixing mute becomes too high, and the heat from the fixing roller and fixing belt is efficiently applied to the unfixed toner image on the transfer material. It is because it is not transmitted.
- Increasing the surface temperature of the fixing roller and the temperature of the heat source of the fixing belt not only violates the requirements for low-temperature fixing properties and energy saving, but also increases the temperature in the image forming apparatus during operation.
- step 3 the roller base material is inserted into the hollow of the cylindrical mold.
- the roller base material 20 is placed in the hollow of a cylindrical mold 20 05 having a heat resistant resin layer 20 3 and an intermediate rubber layer 20 4 formed on the inner surface in this order.
- Insert 1 • An adhesive may be applied to the surface of the roller base.
- it is set so that the center of the cylindrical mold 205 matches the center of the roller base material 201. That is, align the axes of both.
- the pressure roller produced in the example and the comparative example was incorporated in a fixing unit of a commercially available electrophotographic copying machine.
- Fixing rollers arranged in the force p pressure roller and the counter comprises a cylindrical aluminum two ⁇ beam core made, covering opening Ichira member formed by laminating a silicone rubber layer and a fluororesin layer having a thickness of 2 0 of the thickness 2 mm in this order Met.
- the surface temperature of the fluororesin layer of the fixing roller was set to 180 ° C. by a halogen lamp heater arranged in the fixing roller.
- a rubber layer containing an organic microballoon, a heat conductive intermediate rubber layer, a 'and a fluororesin layer (heat-resistant resin layer) are arranged in this order on the substrate.
- a pressure roller was prepared.
- a glass etchant manufactured by Junge Co., Ltd.
- a primer ⁇ DY39-012 manufactured by Toray Dow Cowing Co., Ltd. was applied to the etched surface of the fluororesin coating and air-dried.
- a tetra-etch solution (manufactured by Junye Co.) was applied to the inner surface of the fluororesin coating, and was washed with water and etched. ''
- One-component addition type liquid silicone rubber containing heat conductive filler (Shin-Etsu Chemical Co., Ltd. ⁇ 32-2020) is applied to the inner surface of the fluororesin coating and vulcanized by heating at 160 ° C for 15 minutes. did. In this way, an intermediate rubber layer having a thickness of 10. ⁇ ⁇ m and a thermal conductivity of 1.9 W / m ⁇ K was formed.
- an aluminum core bar (cylindrical Lonilla base material) with an outer diameter of 20 mm ⁇ and a length of 30 Omm
- primer (DY39-012 manufactured by Toray Dow Coung Co., Ltd.) was applied and air-dried.
- This core metal was inserted into the hollow of a cylindrical mold in which a fluororesin film and an intermediate rubber layer were formed so that the axial centers of both coincided.
- Liquid silicone rubber manufactured by Shin-Etsu Chemical Co., Ltd., KE 1 380
- vinylidene chloride-atarilonitrinole copolymer microphone in the gap between the intermediate rubber layer on the inner surface of the cylindrical mold and the core metal Mouth balloon (Matsumoto Yushi Seiyaku Co., Ltd.) 4 volumes. / 0 (based on the total amount) and 5 parts by weight of glycerin (.. ratio to 1'00 parts by weight of liquid silicone rubber) are poured and heated at 160 ° C for 15 minutes to heat the rubber. Sulfurated. Thereafter, the core metal and the rubber layer were removed. The rubber layer had a thermal conductivity of 0.15 W / m.'K.
- the inner surface of a melt-extruded PFA tube (thickness 30 ⁇ , inner diameter 22 mm; using PFA with molecular chain ends made of fluorine atoms) was etched using a metal sodium naphthalene complex and washed with water. 'After that, an adhesive (manufactured by Shin-Etsu Chemical Co., Ltd., Primer 101) was applied to the inner surface and allowed to dry at room temperature for 30 minutes.
- the pressure roller of the present invention can be used as a pressure roller in a fixing unit of an electrophotographic image forming apparatus.
- the pressure roller of the present invention has a rubber layer that is flexible and does not vary in hardness. In addition to being excellent in flexibility, interlayer adhesion, heat resistance, releasability, surface smoothness, durability, etc. Not only low-speed printing but also high-speed printing and full-color printing can be fully handled.
