Patent ID: 8579283

Claim:
An image forming apparatus capable of both side image forming, comprising: an ejected sheet section to which a sheet having an image fixed thereon is ejected; a sheet stacking section to which a sheet remaining in the image forming apparatus is conveyed when jam of the sheet occurs; a main conveyance section to convey a sheet inside the image forming apparatus and to convey the sheet to the ejected sheet section; an orthogonal reverse section to receive the sheet from the main conveyance section and to reverse the sheet without swapping a front edge for a rear edge of the sheet by conveying the sheet in a direction perpendicular to a sheet conveyance direction of the main conveyance section; a reverse sheet conveyance section to convey the reversed sheet from the orthogonal reverse section to an image forming section to fix an image on the sheet, a sheet removing section to remove the reversed sheet from the orthogonal reverse section and discharge the reversed sheet to the sheet stacking section along a direction to turn over the sheet by the orthogonal reverse section when the jam occurs; a jam detection section to detect the jam of the sheet being conveyed in the main conveyance section or the reverse sheet conveyance section; and a control section to control operation of the image forming apparatus; wherein when the jam occurs, the control section conducts remaining sheet ejection control that the main conveyance section or the reverse sheet conveyance section conveys the sheet remaining in the main conveyance section or in the reverse sheet conveyance section which can be conveyed to the orthogonal reverse section without passing through a position where the jam occurs in accordance with a jam position information detected by the jam detection section in case a sheet, other than a jamming sheet, remains in the main conveyance section, the reverse sheet conveyance section, or the orthogonal reverse section.
