PURPOSE:To attain the miniaturization and low revolving speed of a main motor without disturbing a copying action at low cost by adopting a constitution that all of plural loads are not simultaneously applied to the main motor without disturbing the copying action. CONSTITUTION:When paper feeding and drive for an advance are completed and solenoids 52 and 8 are turned off, a solenoid 14 is turned on, an original platen 5 is driven to retreat and retreated up to a position coincident with a copying machine main body and out of the way and a solenoid 8 is intermittently turned on according to the detected toner concentration for a time from the drive for retreating to the stop of the rotational drive of the main motor 1, to replenish toner by a replenishing roller 22. Therefore, the replenishing roller 22, a stirring paddle 23-25 and a feeding roller 36 which are located in the end of the same transmitting system path, respectively are not simultaneously rotated/driven. Moreover, the replenishing roller 22 can not be rotated/driven when the original platen 5 is driven to advance. |
