Embodiment approach 1

[0029] (pressure roller)

[0030] The fixing member in this embodiment is suitable for use in a fixing unit (fixing device) of an image forming apparatus such as an electrophotographic copier and a printer. Thereby, the unfixed toner image can be fixed on a recording medium such as paper by heat and pressure. In this embodiment, a pressure roller is exemplified as a fixing member.

[0031] figure 1 is a cross-sectional view in the circumferential direction showing a configuration example of the fixing member according to Embodiment 1, figure 2 It is an axial cross-sectional view showing a configuration example of the fixing member according to the first embodiment. As shown in the figure, the pressure roller 10 as a fixing member includes a core body 11, an elastic layer 12 formed on the outer peripheral surface of the core body 11, and a release layer 13 formed on the outer peripheral surface of the elastic layer 12, which are stacked in this order from the inner side. T...

[0059] (fixing unit)

[0060] Next, the fixing device according to this embodiment will be described. The fixing device according to the second embodiment includes the pressure roller 10 according to the first embodiment, which is mounted on the image forming device. In addition, the same code|symbol is attached|subjected to the same member as Embodiment 1, and repeated description is abbreviate|omitted.

[0061] image 3 It is a cross-sectional view showing a configuration example of the fixing device according to the second embodiment. Such as image 3 As shown, the fixing device 1 includes: a pressure roller 10, a fixing belt 20 disposed opposite to the pressure roller 10, and at a position opposite to the pressure roller 10, the fixing belt 20 is pressed against the pressure roller 10 from the inside to form a predetermined shape. The pressing member 30 of the nip portion, and the heating means 40 for heating the fixing belt 20 to a predetermined temperature. It shoul...

Embodiment approach 3

[0067] (fixing unit)

[0068] Next, the fixing device according to this embodiment will be described. The fixing device according to the third embodiment includes the pressure roller 10 according to the first embodiment, is mounted on the image forming apparatus, and has a configuration different from that of the fixing device 1 according to the second embodiment. In addition, the same code|symbol is attached|subjected to the same component as Embodiment 2, and repeated description is abbreviate|omitted.

[0069] Figure 4 It is a cross-sectional view showing a configuration example of a fixing device according to Embodiment 3. Such as Figure 4 As shown, the fixing device 2 includes: a pressure roller 10 , a fixing belt 21 disposed opposite to the pressure roller 10 , an inner roller 50 that presses the fixing belt 21 against the pressure roller 10 from the inside, and a heating roller with a built-in heating means 41 . 60. An inner roller 50 and a heating roller 60 are ...

Abstract

An object of the invention is to provide a fixation member which has an unfixed toner fixation function and ensures high releasability, low chargeability, and high friction. The fixation member has anelastic layer 12, and a release layer 13 on the external surface of the elastic layer 12, wherein the release layer 13 is formed of a fluororesin tube having low chargeability and a percent dielectric relaxation of 15% or higher.

Description

technical field [0001] The present invention relates to a fixing member used in a fixing unit of an image forming apparatus such as an electrophotographic copier and a printer. Background technique [0002] Electroforming (Ni (nickel), Ni / Cu (copper) / Ni, PI (polyimide) resin, SUS (stainless steel) ), etc.), an elastic layer, a release layer (fluororesin tube), etc.; a fixing roller, a pressure roller, etc. [0003] The fixing device moves with the rotating pressure roller, the fixing belt (belt-shaped fixing member) heated by the heating means arranged inside rotates, and when the recording medium such as paper passes between the fixing belt and the pressure roller, it passes Heat and pressure are used to fix the unfixed toner. [0004] In such a fixing device, the fixing belt is disposed on the unfixed toner discharge side (toner side) of the recording medium so as to be in direct contact with the unfixed toner. In addition, the pressure roller is arranged on the side op...
