Problems solved by technology

[0016] (1) The wear resistance of the transfer belt or the intermediate transfer belt is not enough;
[0017] (2) Even if an elastic layer is provided on the belt to prevent transfer omission, etc., a resin layer is still used for the surface layer in consideration of cleanability and durability, and the thicker the surface layer, the more impaired the effect of the elastic layer, resulting in Difficult to achieve high image quality;
[0018] (3) The surface layer resin such as fluororesin has high resistance, and if it is formed thickly, it is easy to cause image quality deterioration caused by charging on the belt surface when it is used repeatedly
In addition, in the above publication, only DLC is disclosed with respect to the transfer belt, and there is no disclosure at all about the diamond particles or their particle diameters.

Embodiment 1

[0097] (Example 1: the surface layer adopts the situation of resin dispersed with diamond particles)

[0098] As the above-mentioned diamond fine particles, for example, products manufactured by NEW METAL AND CHEMICALS CO., LTD. or Sumitomo Carbonyl Mining Co., Ltd. can be used. If the diamond particles are manufactured by blasting, there are many impurities and the particle size distribution is relatively wide, so concentrated sulfuric acid is generally used to clean them.

[0099] In addition, there is also a method of synthesizing from graphite using a high-pressure, high-temperature device, but in the embodiments of the present invention, pre-refined diamond particles are used, so the particle preparation process is omitted. These diamond particles can be dispersed in fluorine-based resins such as PFA or PTFE. Furthermore, since it is used as a transfer material, a conductive agent such as carbon can also be dispersed at the same time if necessary.

Embodiment 1a

[0103] (Example 1a: When the present invention is applied to a transfer belt of a direct transfer method)

[0104] exist figure 1 In the configuration of the image forming apparatus shown, a durability test was carried out in a state where development was performed without using toner, and in a state where paper was not passed. Furthermore, once every 1k sheets of paper, a halftone image with an area ratio of 50% was printed on the belt, and the cleaning performance of the belt cleaner was confirmed. At this time, the toner on the cleaned tape was extracted with a mending tape, and the reflection density when the adhesive tape without the toner was attached to white paper was judged to be different from that of the adhesive tape with the toner extracted. Whether the difference between the reflection densities of the bands is maintained at no higher than 0.05.

[0105] Reflection density was measured with a Macbeth densitometer. Randomly measure in five places, as long as on...

Embodiment 1b

[0120] (Example 1b: When the present invention is applied to an indirect transfer belt of an indirect transfer method)

[0121] The above tests were carried out in the figure 1 The configuration shown is performed in a monochrome image forming apparatus. Also, as mentioned above, transfer printing with rubber substrates is mostly used for monochrome structures. Obviously, as long as the chromatic aberration etc. can be accurately controlled, the transfer belt of this constitution can also be used for such as figure 2 The effect of the present invention is also the same as that of the color image forming apparatus having the configuration shown above.

[0122] Moreover, especially in a tandem color image forming apparatus, since the distance between the stages of each color is short, the charging of the belt surface is a serious problem. Also in this case, even if the surface layer using diamond particles is thinner than the conventional fluorine layer, durability can be ac...

Abstract

The transfer member in an image forming apparatus according to an embodiment of the invention is a transfer member in an image forming apparatus for transferring a toner image obtained by developing an electrostatic latent image formed on an image carrier onto a material to be transferred, wherein the transfer member includes a base material having thereon a surface layer for temporarily holding on the surface thereof the toner image to be transferred onto the material to be transferred and comprising a resin containing a diamond fine particle in the range of from about 0.01% to about 40%.

Description

[0001] This application is based on the benefit of priority of US Provisional Application No. 61 / 016734, filed December 26, 2007, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to an image forming device based on electrophotography, and more particularly to a transfer belt and an image forming device using the transfer belt. Background technique [0003] In an electrophotography-based image forming apparatus, a transfer device including an intermediate transfer body such as an intermediate transfer belt or a transfer body such as a transfer belt generally requires a cleaning device. As a cleaning device, a blade (blade) is effective, but its friction is large, so a fluororesin layer is often formed on the surface of the transfer belt. However, the use of fluororesin is not only expensive, but also cannot ensure sufficient wear resistance, and the fluororesin layer will be chipped if it is used repeate...
