A developer recovery device is provided with a recovery container that receives and accommodates a developer recovered from an image carrier, an agitator member that agitates the developer inside the recovery container, two shafts to which mutually engageable cams are respectively provided and that transmit rotational force to the agitator member, a spring that biases and causes to move one of the cams such that the two cams mutually engage and that causes a shaft connection between the two shafts to be joined, a torque limiter that carries out joining of the shaft connection, in which the two cams are caused to mutually engage to join the shaft connection, and disjoining of the shaft connection, in which the two cams are caused to move apart to disjoin the shaft connection, and a full-state determination portion that detects a disjoined state of the shaft connection and, based on the detected disjoined state, determines that the recovery container has become full of developer.
