Abstract: An image forming apparatus includes an apparatus body, a recording head, head tanks, main tanks, liquid feed pumps, a first driving source, a drive control unit, and a drive switching assembly. The drive switching assembly includes a second driving source, a cam, a slider member, a switching gear, switching position detected portions, and a detector. The detected portions are disposed at the cam so as to correspond to switching positions of the liquid teed pumps. One of the detected portions has a greater width in a rotation direction of the cam than any other detected portion. When a time from when the detector detects one of the detected portions to when the detector detects another one of the detected portions is shorter than a threshold value, the drive control unit determines, as a home position, a position of the cam on detection of the another one with the detector.
