Embodiment 1

[0172] (Prepare the ring-shaped substrate)

[0173] A 100 μm-thick, endless belt-shaped substrate containing a conductive substance and made of polyimide (PI) was prepared. As the conductive substance added to the resin material, carbon black can be used. As carbon black, neutral or acidic carbon black can be used. The amount of conductive material used varies depending on the type of conductive material used, but as long as the amount of conductive material added makes the volume resistance value and surface resistance value of the intermediate transfer body reach the specified range, usually, relative to the resin For 100 parts by mass of the material, the amount of the conductive material used is 10 parts by mass to 20 parts by mass, preferably 10 parts by mass to 16 parts by mass. The modulus of elasticity of the matrix is ​​5 GPa.

Embodiment 2

[0228] (Prepare the ring-shaped substrate)

[0229] The same endless belt-shaped substrate as in Example 1 was prepared.

[0230] (Preparation of intermediate transfer body)

[0231] On the prepared annular belt-shaped substrate, change the ratio of the hardness of the surface layer to the hardness of the elastic layer, the hardness of the surface layer, the modulus of elasticity of the surface layer, and the thickness of the surface layer as shown in Table 3 to make a substrate with / elastic layer / surface layer, thus obtaining sample Nos. 201 to 225.

[0232] The hardness and elastic modulus of the surface layer represent values ​​measured by the same method as in Example 1. The thickness of the surface layer represents the value measured by the same method as in Example 1. The thickness and hardness of the elastic layer represent values ​​measured by the same method as in Example 1.

Embodiment 3

[0264] (Prepare the ring-shaped substrate)

[0265] The same endless belt-shaped substrate as in Example 1 was prepared.

[0266] (making elastic layer)

[0267] By the same method, the same elastic layer as the endless belt-shaped base No. 1-3 formed to the elastic layer produced in Example 1 was formed on the prepared endless belt-shaped base, thereby obtaining an endless belt-shaped base. However, nitrile rubber was used as a material, and the film thickness of the elastic layer was 150 μm and the modulus of elasticity was 50 MPa.

[0268] (Preparation of intermediate transfer body)

[0269]When forming the surface layer on the elastic layer formed to the endless belt-shaped base of the elastic layer, as shown in Table 5, the surface layer is made of two layers, the lower layer and the upper layer, and the hardness and elastic modulus of the lower layer are changed. The intermediate transfer body was prepared under the condition of the hardness, elastic modulus, and thic...

Abstract

Provided is an intermediate transcriptional body with high durability, in which the occurrence of a scratch and the occurrence of a crack are suppressed, and which is used for an electro-photographic image forming device with no occurrence of filming. Hence, the intermediate transcriptional body used for the electro-photographic image forming device in which at least an elastic layer and a surface layer are provided on a base in this order characterized in that the elastic modulus of the elastic layer is 10 MPa to 200 MPa, and the thickness thereof is 50 [mu]m to 500 [mu]m.

Description

technical field [0001] The present invention relates to an intermediate transfer body used in an electrophotographic image forming apparatus and a method for manufacturing the intermediate transfer body. Background technique [0002] As an image forming method in image forming apparatuses such as copiers and laser printers, it is known that a toner image formed on a photosensitive drum using a toner with a small particle diameter is first transferred to an intermediate transfer body, and then transferred from the intermediate transfer body to the intermediate transfer body. The transfer method in which the print body is transferred to the transfer material (such as paper) for the second time. [0003] In addition, in recent years, colorization has been developed. Especially in color image forming apparatuses, each toner image formed on a photoreceptor using four-color toners of yellow, magenta, cyan, and black is transferred at a time. After being printed on the intermediat...
