PURPOSE:To drive respective device with a simple operation in the case of collecting developer in a cleaning device, a recycling device and a developing device by interlocking a developing part, a cleaning part and a recycling part with one another in a state where the developing part is separated from a photosensitive body. CONSTITUTION:In the case that the developer is deteriorated by secular change, etc., the old developer remaining in the developing device 2, the cleaning device 3 and the recycling device 4 is collected in the state where the device 2 is separated from the drum 5. At this time, the meshing of a gear 15 with a gear 14 is cancelled and the gear 15 meshes with a gear 20, so that a stirring roller and a sleeve, etc., in the device 2 are interlocked with the devices 3 and 4 as well as at the time of processing for copying. Thus, the respective devices are driven with the simple operation in the case of collecting the developer. |
