Abstract:
A control method of controlling an image forming device, the image forming device includes a shaft extending in a longitudinal direction, an image forming unit that is reciprocally movable along the shaft within a moving region defined by two extremes where the image forming unit reverses, the moving region including a first region, a second region, and a third region between the first region and the second region, a driving mechanism that reciprocally moves the image forming unit and urging means provided in each of the first region and the second region for urging the image forming unit toward a center of the shaft when the image forming unit is in the first region or the second region, wherein the image forming unit is brought into contact with the urging means when moved into the first region or the second region from the third region, the control method comprising the steps of:a) stopping the image forming unit at a predetermined position within the third region; andb) resuming reciprocal movement of the image forming unit by a driving force greater than a repulsive force of the urging means to one of the two extremes closer to the predetermined position.
