Abstract

A toner cartridge for use with an image forming apparatus includes a memory storing identification data of the toner cartridge and parameter information including image formation process parameters dependent on toner characteristic or ambient conditions. A transceiver unit communicates with the image forming apparatus to send the process parameter information stored in the memory to the image forming apparatus when the identification data is authentic.

First claim

What is claimed is:

1. A toner cartridge for use with an image forming apparatus having an acquiring unit configured to acquire inquiry data from the toner cartridge when the toner cartridge is mounted on the image forming apparatus, and a reading unit configured to read parameter information including an image formation parameter, from the toner cartridge when the acquired inquiry data matches inquiry data previously stored in the image forming apparatus, the toner cartridge comprising:
a memory storing the inquiry data of the toner cartridge and the parameter information including the image formation parameter dependent on toner characteristic or ambient conditions, the memory being configured to communicate with the acquiring unit or the reading unit.

2. The toner cartridge of claim 1 , wherein the image formation parameter is one of set values for operations of a photoconductive drum, a developing device, a cleaner, a charger, and a fixing device.

3. The toner cartridge of claim 1 , wherein the image formation parameter is charging voltage values of a charger.

4. The toner cartridge of claim 1 , wherein the image formation parameter is bias voltages of a charger depending on humidity ranges.

5. The toner cartridge of claim 1 , wherein the image formation parameter is associated with a humidity value.

6. A toner cartridge for use with an image forming apparatus having an acquiring unit configured to acquire inquiry data from the toner cartridge; and a reading unit configured to read parameter information including an image formation parameter from the toner cartridge, the toner cartridge comprising:
a memory storing the inquiry data and the parameter information including the image formation parameter, and a table in which at least a value of one of the image formation parameter is associated with a temperature value, the memory being configured to communicate with the acquiring unit or the reading unit.

7. The toner cartridge of claim 6 , wherein the image formation parameter is one of set values for operations of a photoconductive drum, a developing device, a cleaner, a charger, and a fixing device.

8. The toner cartridge of claim 6 , wherein the image formation parameter is charging voltage values of a charger.

9. A toner cartridge for use with an image forming apparatus having an acquiring unit configured to acquire inquiry data from the toner cartridge; and a reading unit configured to read parameter information including an image formation parameter dependent on toner characteristic or ambient conditions, from the toner cartridge, the toner cartridge comprising:
a memory storing the inquiry data and the parameter information including the image formation parameter, and a table in which at least a value of one of the image formation parameter is associated with a humidity value, the memory being configured to communicate with the acquiring unit or the reading unit.

10. The toner cartridge of claim 9 , wherein the image formation parameter is one of set values for operations of a photoconductive drum, a developing device, a cleaner, a charger, and a fixing device.

11. The toner cartridge of claim 9 , wherein the image formation parameter is charging voltage values of a charger.

12. The toner cartridge of claim 9 , wherein the image formation parameter is bias voltages of a charger depending on humidity ranges.
