In a photocopier including a movable member carrying a photoconductive layer, a charging station for charging the layer, an illuminating station for photographically exposing the layer, a developing station provided with a magnetic brush and arranged to supply a magnetic single component toner to the brush for developing the image formed on the layer, a transfer station for transferring the developed image to a record material sheet, and a cleaning station for cleaning the layer, the stations being disposed in succession along the path of movement of the movable member for bringing each portion of the layer into operative association with each station in succession, in combination with a cassette containing a supply of such toner, the developing station is provided with a structure for receiving and holding the cassette in a position for dispensing toner for supply thereof to the magnetic brush, and the cleaning station is provided with a structure for receiving and holding the cassette in a position for collecting residual toner removed from the photoconductive layer in the cleaning station, whereby one and the same cassette can be used to initially supply toner to the developing station and, after having been substantially emptied, can serve as a receptacle for residual toner in the cleaning station.
