Abstract
An image forming apparatus is provided with spring clutches designed to transmit a driving force to a chain by being selectively actuated, whereby a document table is allowed to move at first or second speeds in accordance with the travel of the chain. The image forming apparatus has a microcomputer or controller for controlling first and second spring clutches through solenoids. The controller is provided for changing from the first speed to the second speed, while ensuring that the first spring clutch remains actuated for a predetermined time after the second spring clutch has been actuated.
