PURPOSE:To control the life of a toner dealing unit which can be recycled, to eliminate such waste that the unit is unconditionally discarded and to effectively utilize a resource by providing a count device in the toner dealing unit. CONSTITUTION:The count device(dial, for example) which can repeatedly count the using frequency of the toner dealing unit U is provided in the unit U provided with a tank 7 in which toner can be housed. Besides, the count device 14 is housed in a partitioned space 13 in the tank 7. Therefore, when the unit U is repaired and recycled, the using frequency can be repeatedly counted by the count device 14. Besides, when the count device 14 is housed in the partitioned space 13 in the tank 7, the hystory of the using frequency is held even when the unit U is disassembled. |
