IMAGE FORMING APPARATUS, IMAGE FORMING SYSTEM, AND IMAGE FORMING METHOD |
摘要 |
An image forming apparatus including; a non-inversion conveyance unit that conveys a sheet to a downstream without inverting through the image forming unit; an inversion conveyance unit that inverts the sheet with printing on one side and that conveys the sheet to an upstream; a first sheet inversion unit that is arranged on the inversion conveyance unit and inverts the front and back of the sheet conveyed by the inversion conveyance unit; a control unit that controls the image forming unit and the conveyance unit, wherein the control unit includes a single-sided print mode and a double-sided print mode, and at a breakpoint of jobs, the control unit discharges the sheet so as to provide charge polarity that does not electrostatically attract a sheet discharged just before the breakpoint and a sheet discharged just after the breakpoint at least in the double-sided print mode. |

1. An image forming apparatus comprising:
an image forming unit that prints an image on a sheet based on image data; a conveyance unit comprising: a non-inversion conveyance unit that conveys the sheet to a downstream in a discharge direction without inverting the front and back through the image forming unit; and an inversion conveyance unit that inverts the front and back of the sheet with printing on one side and that conveys the sheet to an upstream in a sheet conveyance direction of the image forming unit; a first sheet inversion unit that is arranged on the inversion conveyance unit and that inverts the front and back of the sheet conveyed by the inversion conveyance unit; and a control unit that controls the image forming unit and the conveyance unit, wherein the control unit includes a single-sided print mode that can print an image on the front of the sheet through conveyance by the non-inversion conveyance unit and a double-sided print mode that can print images on the front and back of the sheet through the conveyance by the non-inversion conveyance unit and inversion conveyance by the inversion conveyance unit, and at a breakpoint of jobs, the control unit discharges the sheet so as to provide charge polarity that does not electrostatically attract a sheet discharged just before the breakpoint and a sheet discharged just after the breakpoint at least in the double-sided print mode. |
