In a copying machine, a container holds toner to be sprinkled on the selenium drum. Toner to replenish the amount consumed in making copies is directed from a supply vessel through a rotary slide valve into an inlet duct for the container. A container pocket for holding the toner supply vessel is mounted on and is rotatable with a part of the valve so that it can be located in an upper and a lower position. In the upper position the valve opens into the inlet duct, however, in the lower position the valve closes the opening into the duct and the supply vessel can be removed from the container pocket. |
