Abstract
An identification method of a recording material container of the present invention sets a recording material container having a first identifying code for storing a recording material in an image forming apparatus, reads the first identifying code in the image forming apparatus, reads an identifying sheet having a recorded second identifying code in the image forming apparatus, and identifies truth or falsehood of the recording material stored in the recording material container on the basis of the relationship between the first identifying code read and the second identifying code.
Claims20
An identification method of a recording material stored in a recording material container used together with an image forming apparatus, comprising:
- reading a first identifying code in an image forming apparatus in which a recording material container storing a recording material and having the first identifying code is set;
- reading an identifying sheet having a recorded second identifying code by a scanner provided in the image forming apparatus;
- and
- identifying truth or falsehood of the recording material stored in the recording material container on the basis of a relationship between the first identifying code and the second identifying code.
A toner supply method of supplying a recording material from a recording material container to a developing unit of an image forming apparatus, comprising:
- reading a first identifying code in an image forming apparatus in which a recording material container storing a recording material and having the first identifying code is set;
- reading an identifying sheet having a recorded second identifying code in the image forming apparatus;
- discriminating a relationship between the read first identifying code and the second identifying code;
- and
- supplying the recording material from the recording material container to the developing unit when it is identified that the read first identifying code and the second identifying code have a predetermined fixed relationship.
An image forming apparatus comprising:
- a recording material container having a first identifying code to store a recording material;
- a developing device supplied with the recording material from the recording material container;
- a code reader to read the first identifying code;
- a scanner to read an identifying sheet on which a second identifying code is recorded;
- and
- an identifying unit to identify truth or falsehood of the recording material stored in the recording material container on the basis of a relationship between the first identifying code read by the code reader and the second identifying code read by the scanner.
An image forming apparatus comprising:
- a recording material container having a first identifying code to store a recording material;
- a developing device supplied with the recording material from the recording material container;
- a code reader to read the first identifying code;
- a scanner to read an identifying sheet on which a second identifying code is recorded;
- a discriminating unit to discriminate a relationship between the first identifying code read by the code reader and the second identifying code read by the scanner;
- and
- a supply unit to supply the recording material from the recording material container to the developing apparatus when it is identified that the read first identifying code and the second identifying code have a predetermined fixed relationship.
