A method of monitoring supply chain activity throughout a plurality of supply chain sites includes extracting, at each supply chain site, supply-related data to be monitored. The data is maintained in plural formats at the supply chain sites, and translated the data to a common format. The extracted data is then uploaded to and collected, from each supply chain site, to a data collection center or site. Upon a user request, a portion of the collected data is formatted, at the data collection site, into one of a plurality of views, responsive to criteria selected by the user, for presentation to the user, the portion of formatted data being dependent on access rights granted to the user's supply chain site. Finally, the formatted data view is published to the user's supply chain site. The data collection center comprises a data collector in which the uploaded data is stored, and a publisher for publishing data from the data collector upon request. Each supply chain site has a data storage device for maintaining its own supply-chain data, a data transfer engine (DTE), for transferring the supply-chain data to the data collection center, input means for allowing a user to query the data collector, and a display for displaying data published by the publisher in response to a query. The inbound data received from the multiple supply chain sites is monitored at the data collection site. If a problem condition is detected, such as a forecasted or present shortage or surplus, an alert is asserted, for example, by highlighting an Alert indicator, such as an Alert tab, on a user screen. Upon selection of the highlighted Alert indicator by a user, details of the detected problem condition are displayed.

Conventionally, the developer in the developer supply container is discharged by an air-supply pump and a suction pump which are provided in the main assembly side of the image forming apparatus, and therefore, the developer is compacted by the increase of the internal pressure of the developer supply container resulting from the air-supply. Therefore, the proper suction of the developer from the developer supply container becomes difficult with the result of shortage of the developer amount to be supplied.

A bellow-like pump is provided on the side of the developer supply container, and the pump alternately repeats the suction operation and the discharging operation through the discharge opening by a driving force inputted from the image forming apparatus side. By this, the developer can be sufficiently loosened, thus properly discharging the developer.

A cartridge is set in a printer main unit, and has a remaining toner measurer which measures toner in a toner chamber upon setting of the cartridge. A cartridge memory stores information of a remaining toner amount measured previously. CPU compares the remaining toner amount measured newly with the remaining toner amount measured previously and read from the cartridge memory. If there is an increase in the toner, the cartridge is determined as improper cartridge reloaded with the toner. An alarm signal is generated. Also, printing is inhibited. In another preferred embodiment, shortage information is assigned to the cartridge upon using up the toner. The cartridge, if it has the shortage information, is determined as improper. If a characteristic of the toner is not within a reference range, the cartridge is determined improper. In another preferred embodiment, an upper limit of the number of times of toner reloading is predetermined. The cartridge is determined improper if the reloading time number comes up to the upper limit. The improper cartridge is set in a state in which operation is inhibited. Also, when the cartridge is disassembled, the improper cartridge is inhibited from operating.
