<p><P>PROBLEM TO BE SOLVED: To improve productivity by setting transporting speeds in a circulation path optimum for various sheet sizes. <P>SOLUTION: This image forming device is equipped with an image forming part, the circulation path for circulating a sheet on which an image is formed to the image forming part again, a re-transporting means provided in the circulation path and transporting the sheet on which the image is formed to the image forming part again, a standby part provided in the circulation path in which the image-formed-sheet is made to standby, a sheet size input part for inputting the sheet size, and a control part for controlling the transporting speed of the re-transporting means so that circulation time of the sheet in the inputted sheet size for one round is included in a range from non-stop circulation time when the sheet is not made to standby in the standby part to maximum standby circulation time when the sheet is made to standby in the standby part for the maximum standby possible time. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
