Endless belt and process for manufacturing the same, image forming apparatus, functional membrane and process for manufacturing the same, intermediate transfer belt, transfer transport belt, and transport apparatus
View Patent ↗An endless belt includes a layer including at least a first composition and a second composition different from the first composition, a content ratio of the second composition relative to the first composition being changed in a layer thickness direction.
1. An endless belt comprising a layer comprising at least a first composition and a second composition different from the first composition, a content ratio of the second composition relative to the first composition being continuously changed in a layer thickness direction,
wherein the first composition and the second composition each comprise at least a resin material and a conductive agent, and the resin material is different in each of the compositions.
2. The endless belt according to claim 1 , wherein a content ratio of the second composition relative to the first composition is linearly changed in a layer thickness direction.
3. The endless belt according to claim 1 , wherein the first composition and the second composition each comprise at least a resin material and a conductive agent, and a content ratio of the conductive agent relative to the resin material is different in each of the compositions.
4. The endless belt according to claim 1 , comprising:
a first layer comprising at least the first composition; and
a second layer formed on the first layer and comprising at least the first composition and the second composition, wherein a content ratio of the second composition relative to the first composition is continuously increased as a distance from the first layer side increases in a layer thickness direction.
5. The endless belt according to claim 4 , further comprising a third layer formed on the second layer and comprising at least the second composition.
6. The endless belt according to claim 1 , comprising:
a belt substrate comprising the first composition;
a first layer formed on the belt substrate and comprising at least the first composition; and
a second layer formed on the first layer and comprising at least the first composition and the second composition, wherein a content ratio of the second composition relative to the first composition is continuously increased as a distance from the first layer side increases in a layer thickness direction.
7. The endless belt according to claim 6 , further comprising a third layer formed on the second layer and comprising at least the second composition.
8. An image forming apparatus comprising the endless belt as defined in claim 1 .
9. A transport apparatus comprising the endless belt as defined in claim 1 , transporting a body to be transported by the endless belt.
10. An intermediate transfer belt comprising a layer comprising at least a first composition and a second composition different from the first composition, a content ratio of the second composition relative to the first composition being continuously changed in a layer thickness direction,
wherein the first composition and the second composition each comprise at least a resin material and a conductive agent, and the resin material is different in each of the compositions.
11. A transfer transport belt comprising a layer comprising at least a first composition and a second composition different from the first composition, a content ratio of the second composition relative to the first composition being continuously changed in a layer thickness direction,
wherein the first composition and the second composition each comprise at least a resin material and a conductive agent, and the resin material is different in each of the compositions.
