1. A tandem-type image forming system performing single-sided printing and double-sided printing on a sheet, the image forming system comprising:
a first image forming apparatus; and a second image forming apparatus connected with the first image forming apparatus in series; wherein when the single-sided printing is performed, one of the first image forming apparatus and the second image forming apparatus performs printing on a sheet; wherein when the double-sided printing is performed, both of the first image forming apparatus and the second image forming apparatus perform the printing on a sheet; wherein the image forming system further comprises a control section which controls a sheet-passing image forming apparatus which is one of the first image forming apparatus and the second image forming apparatus and which does not perform the printing but performs sheet-passing in the single-sided printing; wherein when the single-sided printing is performed, the control section rotates a resist roller and a fixing roller of the sheet-passing image forming apparatus, and controls a component of an image forming section of the sheet-passing image forming apparatus based on a sheet condition, the image forming section being disposed on a sheet carry path between the resist roller and the fixing roller; wherein the sheet condition includes a sheet length in a sub-scanning direction, a sheet basis weight, and a sheet curl amount; wherein the sheet-passing image forming apparatus is a color image forming apparatus; and wherein the component of the image forming section of the sheet-passing image forming apparatus includes yellow, magenta, cyan, and black photosensitive drums, an intermediate transfer belt, and a secondary transfer roller. |
