摘要:
An image forming apparatus comprising: an image forming section which forms an image on a sheet material; a curl correcting mechanism which interposes and conveys the sheet material on which the image has been formed by the image forming section. Pressure applied to one surface of the sheet material during an interposing operation and a conveying speed of the sheet material can be changed, the curl correcting mechanism changes the conveying speed from an initial speed vs to a target speed vo higher than the initial speed (vo > vs) while the sheet material is pressed, and the curl correcting mechanism changes the pressure to a high pressure in response to a change of the conveying speed, whereby a curl of the sheet material is reduced.
摘要:
An image forming system enabling a cost reduction by decreasing the number of components and having enough performance levels of individual postprocessing functions, comprising: an image forming apparatus body (A) and at least one postprocessing unit (B), the postprocessing unit (B) selectable from a plurality of types of postprocessing units, wherein a single-sheet processing machine is provided as one of the plurality of types of postprocessing units and wherein the single-sheet processing machine has a plurality of types of single-sheet processing functions (40,60) for postprocessing in units of a sheet and a sheet attachment function of attaching a cover sheet or an insert sheet to an output sheet bulk.
