An image forming apparatus includes a recording head, head tanks, replaceable main tanks, liquid feed pumps, a first driving source, and a drive switching assembly. The feed pumps feed liquids from the main tanks to the head tanks and in reverse from the head tanks to the main tanks. The drive switching assembly selectively transmits a driving force of the first driving source to the feed pumps. The drive switching assembly includes a second driving source, a cam, a slider member, and a switching gear. The switching gear receives the driving force of the first driving source and is movable with the slider member between positions to engage driving gears of the feed pumps and a position to disengage from the driving gears. With movement of the switching gear, the driving force of the first driving source is selectively transmitted to the feed pumps. |
