Problems solved by technology

[0003] However, a fixing member having sufficient elasticity for obtaining a fixing ability suitable for color images has such a problem that it has poor abrasion resistance and release properties against toner
[0009] PTL 5 discloses a fixing member using an organic-inorganic hybrid material obtained by heating a sol containing a metal alkoxide and a solid silica compound (silica compound) to form a gel as an elastic material, thereby improving Heat resistance and mold release properties, but no practical application yet

Embodiment 1

[0093] A silicone primer layer was formed as a substrate on a cylindrical support (polyimide) of 320 mm length and 50 μm thickness, and dried. Thereafter, fluorosilicone rubber (X36-420U manufactured by Shin-Etsu Chemical Co., Ltd.) was formed to a thickness of 200 μm on the substrate, and heated at 150° C. for 10 minutes.

[0094] The formed fluorosilicone rubber was subjected to plasma treatment under the following conditions.

[0095] Source: PR-500, manufactured by Yamato Scientific Co.

[0096] Output: 100W

[0097] Treatment duration: 4 minutes

[0098] Reactive gas: argon (99.999%)

[0099] Reaction pressure: 10Pa

[0100] On the fluorosilicone rubber, a 0.1% solution of a fluorosilicone compound (OPTOOL DSX, manufactured by Daikin Industries Ltd.) in which the fluorosilicone compound has been diluted with perfluorohexane was applied by the dip coating method, and the withdrawal speed 10mm / min, and then stand in an environment with a temperature of 60°C and a relat...

Embodiment 2

[0110] A fixing member was produced in the same manner as in Example 1, provided that instead of the fluorosilicone rubber, silicone rubber (DY35-2083, manufactured by Toray Industries Inc.) was coated in a thickness of 200 μm, and heated at 150° C. for 30 minutes , and underwent post-curing at 200°C for 4 hours. The manufactured fixing member was evaluated in the same manner as in Example 1.

Embodiment 3

[0112] A fixing member was produced in the same manner as in Example 1, provided that instead of OPTOOL DSX, tetraethoxysilane (ie, tetraethylorthosilicate) (manufactured by Wako Pure Chemical Industries, Ltd.) was applied by dip coating. The produced fixing members were evaluated in the same manner as in Example 1.

Abstract

To provide a fixing member, which contains a base, and a polyorganosiloxane layer provided on the base, where the polyoranosiloxane layer contains polyoranosiloxane including a silicon atom bonded to three or four oxygen atoms, and wherein the fixing member is designed to be used in a process for heating a toner image on a recording medium to fix the toner image onto the recording medium.

Description

technical field [0001] The present invention relates to a fixing device to be installed in an electrophotographic image forming apparatus such as a photocopier, a printer, and a facsimile, and also relates to a fixing member having a high mold release characteristic, which is installed in the fixing device. Background technique [0002] Traditionally, devices applied to electrophotographic systems, such as image forming elements, such as photocopiers, printers, and facsimile machines, usually contain a rotatable photoconductor drum, and the photosensitive layer of the photoconductor drum is uniformly charged, and then emitted from a laser scanning unit. A laser beam exposes the charged photosensitive layer of the photoconductor drum to form an electrostatic latent image on the photoconductor drum. The image forming apparatus further includes a system that operates the following process. That is, after the formed electrostatic latent image is developed with toner, the develo...
