Abstract
An image-forming apparatus includes a coupling recess to be engaged with a coupling protrusion to rotate the coupling protrusion, a second gear portion to be engaged with a gear to rotate the gear, and a driving force transmitter that is rotatable about a predetermined rotational axis. A torque required to rotate the gear is larger than a torque required to rotate the second gear portion in a state where the coupling recess does not engage the coupling protrusion.
