Abstract

An electrostatic image-developing toner comprising a binder resin, wherein the content of all the chlorine-substituted benzene derivatives in the electrostatic image-developing toner is about 0.01 ppb or more and about 10 ppb or less.

Claims (26)

1. An electrostatic image-developing toner comprising

chlorine-substituted benzene derivatives;

a binder resin; and

a pigment selected from the group consisting of C. I. Pigment Green 7, C. I. Pigment Green 36, and C. I. Pigment Orange 61,

wherein the content of all the chlorine-substituted benzene derivatives in the electrostatic image-developing toner is about 0.01 ppb or more and about 10 ppb or less.

2. An electrostatic image developer comprising the toner according to claim 1 and a carrier.

3. A toner cartridge comprising the electrostatic image-developing toner according to claim 1 .

4. A process cartridge comprising:

a developing unit for developing the electrostatic latent image with the electrostatic image developer according to claim 2 to form a toner image.

5. An image-forming method comprising:

a charging process for charging a photoreceptor,

an exposing process for exposing the charged photoreceptor to form a latent image on the photoreceptor,

a developing process for developing the latent image to form a developed image,

a transfer process for transferring the developed image to a transfer-receiving member, and

a fixing process for fixing a toner on a fixation base material by heating,

wherein the toner is the electrostatic image developing toner according to claim 1 .

6. An image-forming apparatus comprising:

a latent image-forming unit for forming a latent image on a latent image holding member,

a developing unit for developing the latent image into a developed toner image with an electrostatic image developer,

a transfer unit for transferring the developed toner image to a transfer-receiving member through or not through an intermediate transfer member, and

a fixing unit for fixing the toner image on the transfer-receiving member,

wherein the electrostatic image developer is the electrostatic image developer according to claim 2 .

7. The electrostatic image-developing toner according to claim 1 , wherein the content of all the chlorine-substituted benzene derivatives in the electrostatic image-developing toner is 0.1 ppb or more and 3 ppb or less.

8. The electrostatic image-developing toner of claim 1 , wherein the pigment is C. I. Pigment Green 7.

9. The electrostatic image-developing toner of claim 1 , wherein the pigment consists of C. I. Pigment Green 7 only.

10. The electrostatic image-developing toner of claim 1 , wherein the binder resin is a polyester resin or a styrene-acrylate resin.
