1. A toner bottle cap:
a fixed member, the fixed member being stationary relative to a toner bottle and defining a first flow passage for toner; and a slide member, the slide member defining a second flow passage coaxially adjoining the first flow passage in a toner outflow direction and having a peripheral wall in sealing contact with a peripheral wall of the fixed member, the slide member being slideable relative to the fixed member in axial direction of the first and second flow passages, wherein one of the fixed member and the slide member has a wall part that restricts the cross-section of the flow passage of said one member and defines a toner outflow opening, and the other of the fixed member and the slide member has a stop member that projects axially towards the outflow opening and closes the outflow opening when the slide member is in a closed position and opens the outflow opening when the slide member is slid in the toner outflow direction. |
