Abstract

A toner includes a resin having an unsaturated double bond, a thiol compound having a bi- or more-functional thiol group, and a polymerization initiator.

Claims (41)

1. A toner comprising:

a resin having an unsaturated double bond;

a thiol compound comprising a bi- or more-functional thiol group; and

a polymerization initiator.

2. The toner according to claim 1 , further comprising a vinyl resin.

3. The toner according to claim 1 , further comprising a radical polymerizable material.

4. A liquid developer comprising:

the toner according to claim 1 ; and

a carrier solution.

5. A dry developer comprising

the toner according to claim 1 .

6. A developer cartridge containing the liquid developer according to claim 4 .

7. A developer cartridge containing the dry developer according to claim 5 .

8. A process cartridge containing the liquid developer according to claim 4 .

9. A process cartridge containing the dry developer according to claim 5 .

10. An image forming apparatus comprising:

an image holding member;

a latent image forming unit that forms a latent image on a surface of the image holding member;

a developing unit that forms a toner image by developing the latent image, which is formed on the surface of the image holding member, using the liquid developer according to claim 4 ;

a transfer unit that transfers the toner image, which is formed on the surface of the image holding member, onto a recording medium;

a fixing unit that forms a fixed image by fixing the toner image, which is transferred onto the recording medium, on the recording medium; and

a curing unit that cures the fixed image.

11. An image forming apparatus comprising:

an image holding member;

a latent image forming unit that forms a latent image on a surface of the image holding member;

a developing unit that forms a toner image by developing the latent image, which is formed on the surface of the image holding member, using the dry developer according to claim 5 ;

a transfer unit that transfers the toner image, which is formed on the surface of the image holding member, onto a recording medium;

a fixing unit that forms a fixed image by fixing the toner image, which is transferred onto the recording medium, on the recording medium; and

a curing unit that cures the fixed image.

12. An image forming method comprising:

forming a latent image on a surface of an image holding member;

forming a toner image by developing the latent image, which is formed on the surface of the image holding member, using the liquid developer according to claim 4 ;

transferring the toner image, which is formed on the surface of the image holding member, onto a recording medium;

forming a fixed image by fixing the toner image, which is transferred onto the recording medium, on the recording medium; and

curing the fixed image.

13. An image forming method comprising:

forming a latent image on a surface of an image holding member;

forming a toner image by developing the latent image, which is formed on the surface of the image holding member, using the dry developer according to claim 5 ;

transferring the toner image, which is formed on the surface of the image holding member, onto a recording medium;

forming a fixed image by fixing the toner image, which is transferred onto the recording medium, on the recording medium; and

curing the fixed image.
