PROBLEM TO BE SOLVED: To prevent the scattering of toner at the time of dismantling an image forming device by providing a control means for forcibly actuating a toner carrying means for a specified time. SOLUTION: At the time of dismantling the image forming device 1, a toner forcible supply control is previously stored in the storage part of the control means first. The toner forcible supply control is to perform toner supply independently of toner supply control to a developing device 5 by detecting toner concentration by a toner concentration sensor 13. Then, the toner supply is forcibly performed for the specified time regardless of toner concentration detected by the sensor 13. In order to execute the toner forcible supply control, a control panel is operated to input a toner forcible supply signal in the control means. Therefore, the scattering of the toner from 1st and 2nd toner hopper parts is prevented because the toner in the device 1 is mostly collected to the device 5 by moving the device 1 after finishing the toner forcible supply control. |
