Abstract

A transfer belt includes a substrate layer that includes polyester, silicone particles, and conductive particles.

First claim

What is claimed is:

1. A transfer belt comprising,
a substrate layer that includes polyester, silicone particles, and conductive particles,
wherein the silicone particles include a core portion and a shell portion, in which the core portion includes a silicone resin not having a three-dimensional crosslinked structure and the shell portion coats the core portion and includes a silicone resin having a three-dimensional crosslinked structure.

2. The transfer belt according to claim 1 ,
wherein the polyester is polyester including an aromatic group.

3. The transfer belt according to claim 2 ,
wherein the polyester including an aromatic group is polybutylene terephthalate.

4. The transfer belt according to claim 1 ,
wherein the conductive particles are particles of a carbon material.

5. A transfer belt comprising,
a substrate layer that includes polyester, silicone particles, and conductive particles,
wherein a mass ratio Mc/Ms of a content Mc of the conductive particles to a content Ms of the silicone particles is 0.5 or more and 30 or less.

6. The transfer belt according to claim 1 ,
wherein in a case where a content of the polyester is set to 100 parts by mass,
a content of the silicone particles is 1 part by mass or more and 30 parts by mass or less, and
a content of the conductive particles is 15 parts by mass or more and 40 parts by mass or less.

7. A transfer device comprising:
an intermediate transfer belt that includes the transfer belt according to claim 2 ;
a primary transfer device that primarily transfers a toner image formed on a surface of an image holder to an outer peripheral surface of the intermediate transfer belt; and
a secondary transfer device that secondarily transfers the toner image transferred to the outer peripheral surface of the intermediate transfer belt to a recording medium.

8. A transfer device comprising:
an intermediate transfer belt that includes the transfer belt according to claim 3 ;
a primary transfer device that primarily transfers a toner image formed on a surface of an image holder to an outer peripheral surface of the intermediate transfer belt; and
a secondary transfer device that secondarily transfers the toner image transferred to the outer peripheral surface of the intermediate transfer belt to a recording medium.

9. A transfer device comprising:
an intermediate transfer belt that includes the transfer belt according to claim 1 ;
a primary transfer device that primarily transfers a toner image formed on a surface of an image holder to an outer peripheral surface of the intermediate transfer belt; and
a secondary transfer device that secondarily transfers the toner image transferred to the outer peripheral surface of the intermediate transfer belt to a recording medium.

10. A transfer device comprising:
an intermediate transfer belt that includes the transfer belt according to claim 4 ;
a primary transfer device that primarily transfers a toner image formed on a surface of an image holder to an outer peripheral surface of the intermediate transfer belt; and
a secondary transfer device that secondarily transfers the toner image transferred to the outer peripheral surface of the intermediate transfer belt to a recording medium.

11. A transfer device comprising:
an intermediate transfer belt that includes the transfer belt according to claim 5 ;
a primary transfer device that primarily transfers a toner image formed on a surface of an image holder to an outer peripheral surface of the intermediate transfer belt; and
a secondary transfer device that secondarily transfers the toner image transferred to the outer peripheral surface of the intermediate transfer belt to a recording medium.

12. A transfer device comprising:
an intermediate transfer belt that includes the transfer belt according to claim 6 ;
a primary transfer device that primarily transfers a toner image formed on a surface of an image holder to an outer peripheral surface of the intermediate transfer belt; and
a secondary transfer device that secondarily transfers the toner image transferred to the outer peripheral surface of the intermediate transfer belt to a recording medium.

13. An image forming apparatus comprising:
the transfer device according to claim 7 .

14. An image forming apparatus comprising:
the transfer device according to claim 8 .

15. An image forming apparatus comprising:
the transfer device according to claim 9 .

16. An image forming apparatus comprising:
the transfer device according to claim 10 .

17. An image forming apparatus comprising:
the transfer device according to claim 11 .
