PURPOSE:To notify a user that an integration part is completely full of toner by judging that the integration part is completely full of the integrated developer based on a signal outputted from a detection means and stopping an image forming action. CONSTITUTION:During the action of an image forming device, the residual developer T on an image carrier 7 is removed by a blade 40, etc., of a cleaning device 13 and the removed developer T is conveyed to the integration part 49 by a conveying means 45. When the integration part 49 is completely full of the developer T, the developer T is flucculated and a load is given to the conveying means 45 by the developer T. In such a case, since a driving means 46 steps out and an output signal from the detection means R changes, a processing means judges that the integration part is completely full of the developer T and stops the action of the image forming device, then it makes a display part display that said part 49 is completely full of the developer. Thus, the toner is not leaked at the time of conveying and integrating the residual toner and the user can be notified that the integration part is completely full of toner by stably detecting it at a toner fullness set level. |
