| 发明名称 | Electrophotographic member and fixing apparatus | ||
| 摘要 | The present invention relates to an electrophotographic member having electroconductivity for suppressing peeling offset and also having a high cracking resistance. The electrophotographic member has an endless belt shape, and includes a cylindrical or columnar substrate, a rubber elastic layer that covers a periphery of the substrate, and a fluororesin tube that covers a periphery of the rubber elastic layer, wherein the fluororesin tube is crystalline-orientated in a substantially axial direction of the substrate and includes a fluororesin and carbon black dispersed in the fluororesin, and a primary average particle diameter of the carbon black is 50 nm or more and 100 nm or less. | ||
