摘要： An image forming apparatus includes first and second image forming portions. A first conveying pipe conveys a first developer discharged from a first developing unit to a collection portion, and a second conveying pipe conveys a second developer discharged from a second developing unit to the collection portion. A first detection unit detects a toner content of the first developer in the first conveying pipe, and a second detection unit detects a toner content of the second developer in the second conveying pipe. The first developing unit can be removed from the image forming apparatus in a state that the first conveying pipe and the first detection unit remain in the image forming apparatus, and the second developing unit can be removed from the image forming apparatus in a state that the second conveying pipe and the second detection unit remain in the image forming apparatus.

摘要： A toner cartridge comprises toner and electrical development components which consume a portion of the toner by printing a plurality of images. An electronic circuit stores an indication of the amount of toner remaining, and a value controlling a voltage applied to at least one of the electrical development components. The electronic circuit determines when a predetermined amount of the toner remains in the toner cartridge. When the predetermined amount of toner remains in the toner cartridge, the electronic circuit alters the amount of toner consumed to form images by changing a voltage level applied to at least one of the electrical development components. The electronic circuit alters the amount of toner consumed by replacing the stored value controlling the voltage applied to at least one of the electrical development components with a new value controlling the voltage applied to at least one of the electrical development components.
