Drive Transmission Device That Ensures Switching Transmission State of Driving Power Generated by Single Drive Motor, and Image Forming Apparatus Therewith
A drive transmission device includes a driving power receiver, a first rotator drive transmission system, and a second rotator drive transmission system. The driving power receiver directly receives the driving power from an output shaft of the drive motor. The first rotator drive transmission system is configured to transmit the driving power from the driving power receiver to the respective first rotators of the first structure and the second structure. The second rotator drive transmission system is configured to switch a state of transmission of the driving power from the driving power receiver into a first transmission state in which the driving power is transmitted to the respective second rotators of the first structure and the second structure, and into a second transmission state in which the driving power is transmitted to the second rotator of the first structure alone.
