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 feed 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.

Abstract: An image formation device is configured such that a length of a sheet feed path from a sheet accommodation unit to a sheet detection unit is greater than the sheet distance for a predetermined type sheet that has substantially the same sheet length as a maximum size sheet employable in the image formation unit. A sheet length of the sheet fed by the sheet feed mechanism is measured. If the sheet length of a firstly fed sheet, which is fed in response to an image formation instruction and measured by the measuring unit, is equal to the sheet length of the predetermined type of sheet, the control unit feeds a subsequent sheet with the sheet distance corresponding for the maximum size sheet between a trailing end of the previously fed sheet and the leading end of the subsequent sheet.
