PURPOSE: To provide an image forming device where a rotating body is surely cleaned by a cleaning sheet. CONSTITUTION: A control part 11 judges the completion of the exchange of an exchangeable unit (for example, a developing unit, etc.) constituting the image forming device, controls a driving device 18 so that the cleaning sheet may be ejected to the outside of a machine after completing the exchange of the unit, performs control that only manual paper feeding operation is accepted after the cleaning sheet is ejected to the outside of the machine, discriminates whether the sheet taken in the machine is the cleaning sheet or not by using a sensor 3, and controls so that the operation is not shifted to ordinary image forming operation until judging that the sheet taken in the machine is the cleaning sheet. |
