Abstract:
1. A recording material moving device, comprising: a position adjuster that moves a recording material in a direction which is parallel to a recording surface of the recording material and orthogonal to a transporting direction, in an upstream side of a recording position along the conveying direction of the recording material, the recording position being where an image is formed on the recording material; a reference position specifying unit that specifies a reference position which is taken as a reference when the transport unit moves the recording material; a determination unit that determines whether a range of a predetermined width centered on the reference position specified by the reference position specifying unit exceeds a movable range of the recording material within which the recording material can be moved by the position adjuster; and a controller that causes, if the determination unit determines that the range of the predetermined width does not exceed the movable range, the position adjuster to sequentially move the recording material within the movable range of the predetermined width centered on the reference position each time a condition for moving the recording material is satisfied, or causes, if the determination unit determines that the range of the predetermined width exceed the movable range, the position adjuster to sequentially move the recording material within the range of the predetermined width, which is included in the movable range and includes the reference position, each time the condition for moving the recording material is satisfied, wherein; the controller calculates a first position group as a move position group if the determination unit determines that the range of the predetermined width does not exceed the movable range, the first position group including a predetermined number of positions which are discretely arranged throughout the predetermined width centered on the reference position, or the controller calculates a second position group as a move position group if the determination unit determines that the range of the predetermined width exceeds the movable range, the second position group including a predetermined number of positions which are discretely arranged throughout the predetermined width toward the opposite limit of the movable range from a position which does not exceed the movable range and is closest to the limit of the movable range, and each time the condition for moving the recording material is satisfied, the controller causes the position adjuster to sequentially move the recording material to a next position in the positions included in the move position group.
