PROBLEM TO BE SOLVED: To provide a developer supply cartridge T configured to detect an opened/closed state of a supply-side shutter unit 50 arranged to open/close a developer supply opening 43 of the developer supply cartridge T.SOLUTION: A developer supply cartridge T includes a supply-side shutter unit 50 which moves when the developer supply cartridge T moves between a closed position for closing a developer supply-side opening 43 and an open position for opening the opening 43 with a predetermined opening width so as to supply/discharge developer when mounted on a mounting position of the developer supply cartridge T. The developer supply cartridge T includes an input electrode unit 51, an output electrode unit 52, and a connection unit which switches an electric connection state between the electrodes as a supply valve moving member 48 moves. An electric connection state between the input electrode unit 51 and the output electrode unit 52 is associated with an opened/closed state of the supply-side shutter unit 50 when the developer supply cartridge T is located in the mounting position. |
