Abstract

An image forming apparatus mounted with a toner cartridge having a memory unit includes a toner cartridge which stores a plurality of control data depending on toner in the memory unit, an acquisition unit which selects one of the plurality of control data in the memory unit and acquires image formation-related information and a setting unit which sets image formation parameters on the basis of the image formation-related information.

Claims

1. A toner cartridge for use with an image forming apparatus having an acquiring unit configured to acquire identification data from the toner cartridge when the toner cartridge is mounted on the image forming apparatus;

a reading unit configured to read parameter information including image formation process parameters, from the toner cartridge when the acquired identification data matches identifying data previously stored in the image forming apparatus, and not read the parameter information from the toner cartridge when the acquired identification data does not match the identifying data, the toner cartridge comprising;

a memory storing the identification data of the toner cartridge and the parameter information including the image formation process parameters dependent on toner characteristic or ambient conditions, the memory being configured to communicate with the acquiring unit or the reading unit by wire.

2. The toner cartridge of claim 1, wherein the memory stores a table in which at least a value of one of the image formation process parameters is associated with a temperature value.

3. The toner cartridge of claim 1, wherein the memory stores a table in which at least a value of one of the image formation process parameters is associated with a humidify value.

4. The toner cartridge of claim 1, wherein the memory stores a table in which at least a value of one of the image formation process parameters is associated with a life time.

5. The toner cartridge of claim 1, wherein the memory stores a table in which at least a value of one of the image formation process parameters is associated with a number of printed sheets.

6. The toner cartridge of claim 1, wherein the toner characteristic is toner resistance.

7. The toner cartridge of claim 1, wherein the toner characteristic is a particle diameter of toner.

8. The toner cartridge of claim 1, wherein the toner characteristic is a lot number for manufacturing toner.

9. The toner cartridge of claim 1, wherein the parameter information is based on color information.

10. A toner cartridge for use with an image forming apparatus having an acquiring unit configured to acquire identification data from the toner cartridge;

and a reading unit configured to read parameter information including image formation process parameters from the toner cartridge, the toner cartridge comprising;

a memory storing the identification data and the parameter information including the image formation process parameters, and a table in which at least a value of one of the image formation process parameters is associated with a temperature value, the memory being configured to communicate with the acquiring unit or the reading unit by wire.

11. A toner cartridge for use with an image forming apparatus having an acquiring unit configured to acquire identification data from the toner cartridge;

and a reading unit configured to read parameter information including image formation process parameters dependent on toner characteristic or ambient conditions, from the toner cartridge, the toner cartridge comprising;

a memory storing the identification data and the parameter information including the image formation process parameters, and a table in which at least a value of one of the image formation process parameters is associated with a humidity value, the memory being configured to communicate with the acquiring unit or the reading unit by wire.

12. An image forming apparatus comprising:

an acquiring unit which acquires identification data from a toner cartridge, when the toner cartridge is mounted on the image forming apparatus, the toner cartridge comprising a memory storing the identification data of the toner cartridge and parameter information including image formation process parameters dependent on toner characteristic or ambient conditions; and

a reading unit which reads the parameter information including the image formation process parameters from the toner cartridge when the acquired identification data matches identifying data previously stored in the image forming apparatus, and not read the parameter information from the toner cartridge when the acquired identification data does not match the identifying data, the memory being configured to communicate with the acquiring unit or the reading unit by wire.
