The developer unit includes a drive force input unit and a drive force transmitting unit. A drive force is inputted into the drive force input unit from outside of the developer unit. The drive force transmitting unit transmits the drive force. The switching member is for switching the drive force transmitting unit between a transmitting state and an interrupting state. The switching member switches the drive force transmitting unit to the transmitting state when the developer unit is at the image-forming position, and the switching member switches the drive force transmitting unit to the interrupting state when the developer unit is at the detached position.
