PROBLEM TO BE SOLVED: To perform drive switching in a short period of time when performing drive switching between different rotation directions by one driving source.SOLUTION: An image forming device is provided with one DC motor 700, and a driving force transfer mechanism 800 for selectively transferring driving force to a reciprocation mechanism 801 for slidingly moving a cap advancing and retracting mechanism 802 of a first maintenance recovery part 21 or a second maintenance recovery part 22 by switching a drive transfer path by a normal rotation and a reverse rotation of the DC motor 700. The driving force transfer mechanism 800 includes at least two ratchet mechanisms 605a, 605b which transfer rotations in one direction and do not transfer rotations in the other direction, and driving control means 900 for performing driving control of the DC motor 700, and when stopping the DC motor 700, and driving the cap advancing and retracting mechanism 802 and next driving the reciprocation mechanism 801, rotates the DC motor 700 in a direction opposite to a direction before stop for only a prescribed time T shorter than a time required for the ratchet mechanism 605a to transition from a disconnected state to a connected state . |
