The figure shows an embodiment of the consumable cartridge of the present invention. FIG. 5(a) is a side view, and FIG. 1(b) is a plan view. The consumable cartridge 9 has a cylindrical drum as an information recording section 1, and a barcode label 2 recording a barcode pattern is attached to the surface of the drum.
．． It rotates in synchronization with the photosensitive drum 7 via the second gear 6. The photosensitive drum 7 is driven by a driving force transmitted from the main body of the apparatus by a gear (not shown). The consumable cartridge 9 has an opening 8 as a reading section in which the light from the light source 4 that illuminates the barcode label 2 and the optical signal of the information recorded on the barcode label 2 are emitted from the apparatus main body side to the optical sensor 3. The recorded information on the barcode label 2 can be read by the main unit. Consumable cartridge 9
When the photosensitive drum 7 is replaced and attached to the main body of the apparatus or the power of the main body is turned on, the photosensitive drum 7 is usually rotated about one revolution without printing in order to initialize the photosensitive drum 7. , At this time, the information recording section 1 is also driven at the same time, and the information on the barcode label 2 is read by the optical sensor 3. This information records the unique characteristics of the consumable cartridge 9, such as the optimum developing bias information for the photosensitive drum 7, so that the optimum process conditions can be set for the cartridge. This information can also include a unique ID number for each cartridge, and by storing the cumulative lifespan of consumables for each ID number on the device side, it is possible to insert multiple consumables cartridges in the middle of their lifespan. Even if the cartridge is used while being replaced, the lifespan of each cartridge can be correctly managed.
