Abstract:
1. A sheet conveying apparatus, which conveys a sheet on which an image is formed on a first surface by an image forming portion toward the image forming portion again for forming an image on a second surface of the sheet, comprising: a first conveying path configured to guide the sheet on which the image is formed on the first surface; a sheet reverse conveying portion which conveys a sheet, which has been guided by the first conveying path, in a first direction, and thereafter conveys the sheet in a second direction opposite the first direction; a second conveying path configured to guide the sheet conveyed by the reverse conveying portion in the first direction and the second direction; a third conveying path configured to guide the sheet conveyed from the second conveying path in the second direction by the sheet reverse conveying portion, the second conveying path conveying the sheet to the image forming portion for forming the image on the second surface; and a guide portion configured to guide the conveyed sheet, the guide portion being movable and being provided between the first conveying path and the second conveying path, the guide portion contacting with an identical surface side of the sheet when the sheet is guided from the first conveying path to the second conveying path and when the sheet is guided from the second conveying path to the third conveying path, wherein the guide portion is moved to a position where the guide portion guides the sheet to the third conveying path while blocking between the second conveying path and the first conveying path such that the sheet can not intrude from the second conveying path into the first conveying path when the sheet conveyed by the sheet reverse conveying portion is conveyed in the second direction, and the guide portion is moved to form a route connecting the first conveyance path and the second conveyance path by a sheet which is conveyed in the first conveyance path toward the second conveyance path.
