ABSTRACT:
An image forming apparatus includes: a liquid tank which retains a liquid; a liquid jetting head connected to the liquid tank and having a nozzle for jetting the liquid; a carriage on which the liquid tank and the liquid jetting head are provided; a recovery mechanism which recovers the liquid jetting head; a memory which retains predetermined history information; and a controller which controls the recovery mechanism based on the history information. The recovery mechanism selectively executes a first recovery operation for discharging air from the liquid tank and a second recovery operation for discharging air from the liquid tank and for discharging the liquid from the nozzle, and the controller controls the recovery mechanism to perform the first recovery operation if the history information in the memory includes an abnormality when a power of the image forming apparatus is switched ON.
