Abstract

An organic photoconductor includes a cylindrical body having a surface on which an electrostatic latent image is to be formed, and an optical tag provided on an outer circumferential surface of the cylindrical body. The organic photoconductor may be included in a development cartridge for an image forming apparatus.

First claim

What is claimed is:

1. A photoconductor comprising:
a cylindrical body having a surface on which an electrostatic latent image is to be formed; and
an optical tag provided on an outer circumferential surface of the cylindrical body, wherein the optical tag comprises a dye layer and a reflective layer.

2. The photoconductor of claim 1 , wherein the optical tag is provided at an end of the cylindrical body.

3. The photoconductor of claim 1 , wherein the optical tag includes a read-write surface to which data is writable from an optical device to the optical tag.

4. The photoconductor of claim 1 , wherein the cylindrical body includes a plurality of layers, the plurality of layers comprising:
a blocking layer provided along an entire length of the cylindrical body,
a charge generation layer provided along a first portion of the length of the cylindrical body, and
a charge transport layer provided along the first portion of the length of the cylindrical body.

5. The photoconductor of claim 4 , wherein the plurality of layers comprise:
the dye layer, the reflective layer, and a protective layer provided along a remaining portion of the length of the cylindrical body.

6. A development cartridge, comprising:
the photoconductor of claim 1 ; and
a developing roller to transfer toner to the electrostatic latent image formed on the surface of the cylindrical body to form a visible toner image on the surface of the cylindrical body.

7. The development cartridge of claim 6 , wherein the cylindrical body includes a plurality of layers, the plurality of layers comprising:
a blocking layer provided along a length of the cylindrical body,
a charge generation layer provided along a first portion of the length of the cylindrical body, and
a charge transport layer provided along the first portion of the length of the cylindrical body.

8. The development cartridge of claim 7 , wherein the plurality of layers comprise:
the dye layer, the reflective layer, and a protective layer provided along a remaining portion of the length of the cylindrical body.

9. The development cartridge of claim 6 , wherein:
the optical tag is to store data, the data including at least one of authentication data, use information relating to the photoconductor, or job information relating to an image forming job performed using the development cartridge, and
the optical tag includes:
a read-only surface from which data stored in the optical tag is readable by an optical device, or
a read-write surface from which data stored in the optical tag is readable by the optical device and to which data can be written from the optical device to the optical tag.

10. A photoconductor comprising:
a cylindrical body having a surface on which an electrostatic latent image is to be formed; and
an optical tag provided on an outer circumferential surface of the cylindrical body, wherein the optical tag comprises a dielectric film, a phase change material, and a reflective layer.

11. The photoconductor of claim 10 , wherein the cylindrical body includes a plurality of layers, the plurality of layers comprising:
a blocking layer provided along a length of the cylindrical body,
a charge generation layer provided along a first portion of the length of the cylindrical body, and
a charge transport layer provided along the first portion of the length of the cylindrical body.

12. The photoconductor of claim 11 , wherein the plurality of layers further comprise:
the dielectric film, the phase change material, the reflective layer, and a protective layer provided along a remaining portion of the length of the cylindrical body.

13. An image forming apparatus comprising:
a main body;
a photoconductor comprising:
a cylindrical body having a surface on which an electrostatic latent image is to be formed, and
an optical tag provided on an outer circumferential surface of the cylindrical body; and
an optical device to emit a first light to write data to the optical tag, and to emit a second light to read the data from the optical tag.

14. The image forming apparatus of claim 13 , wherein the second light has an intensity less than the first light.

15. The image forming apparatus of claim 13 , wherein the data to be read from the optical tag and/or the data to be written to the optical tag includes at least one of authentication data, use information relating to the photoconductor, or job information relating to an image forming job performed by the image forming apparatus.

16. The image forming apparatus of claim 13 , wherein the optical tag comprises a dye layer and a reflective layer.

17. The image forming apparatus of claim 13 , wherein the optical tag comprises a dielectric film, a phase change material, and a reflective layer.

18. A method for manufacturing a photoconductor, comprising:
providing a cylindrical body;
applying a blocking layer along an entire length of the cylindrical body;
applying at least one of a charge generation layer and a charge transport layer along a first portion of the length of the cylindrical body; and
providing an optical tag on an outer circumferential surface of a remaining portion of the length of the cylindrical body, the optical tag comprising a read-write surface on which data is writable based on a first light emitted by an optical device, and from which data is readable based on a second light emitted by the optical device.

19. The method of claim 18 , wherein providing the optical tag comprises:
applying a dye layer, a reflective layer, and a protective layer along the remaining portion of the length of the cylindrical body.

20. The method of claim 18 , wherein providing the optical tag comprises:
applying a dielectric film, a phase change material, a reflective layer, and a protective layer along the remaining portion of the length of the cylindrical body.
