Abstract
An image-forming apparatus includes: a photosensitive drum, a motor, and a drum gear train configured to transmit a driving force from the motor to the photosensitive drum. The drum gear train includes a first gear, a second gear and a first clutch. The first gear is rotatable about a first axis upon receipt of the driving force. The second gear is rotatable about the first axis and configured to receive the driving force from the first gear and to transmit the driving force to the photosensitive drum. The first clutch is switchable between a first transmission state where the driving force is transmitted from the first gear to the second gear and a first transmission cutoff state where the transmission of the driving force from the first gear to the second gear is cut off.
