PROBLEM TO BE SOLVED: To provide a developing device capable of peeling a sealing body from a toner cartridge just by easy operation that the toner cartridge is attached to the developing device and exchanging the toner cartridge without soiling a hand. SOLUTION: The toner cartridge (9) is attached to the developing device (1) and a driving shaft (14) from the driving source (13) of the device (1) is coupled with the coupling shaft (16) of a supply means (15). The driving source (13) starts driving according to a toner supply signal from the device (1) and the supply means (15) is driven, then a take-up shaft (12) is turned by a driving transmitting means (18) according to such driving action. Since the leading edge of the sealing body (11) is previously fixed on the shaft (12), the sealing body is successively taken up by the turning of the shaft (12). |
