Toner refill device

A toner refill device comprising:

• a first adapter unit defining a first refill opening;
• a first closure member attached to the first adapter unit and movable between a closed position in which the first adapter unit closes the first refill opening, and an open position;
• a second adapter unit defining a second refill opening;
• a second closure member attached to the second adapter unit and movable between a closed position in which the second adapter unit closes the second refill opening and an open position, said second closure member having a passage forming element that connects the first and second refill openings when the second closure member is in the open position,
• wherein the second adapter unit defines an accommodation space for accommodating the passage forming element when the second closure member is in the closed position,
• wherein the first and second closure members are adapted to be coupled to one another for a joint movement relative to the first and second adapter units, and
• wherein the first and second closure members are rotatably supported in their respective adapter units, so as to be jointly rotatable about a common axis of rotation, and the second refill opening and the accommodation space are angularly offset from one another about said common axis of rotation.
