Abstract:
1. An image forming apparatus comprising: a sheet feed section that includes a sheet feed cassette and a manual feed tray and that is configured to feed a sheet stored in the sheet feed cassette or a sheet loaded onto the manual feed tray; a sheet conveyance section that is configured to convey the sheet fed by the sheet feed section and that includes a sheet reversing mechanism for reversing sides of the sheet; a reception section configured to receive input pertaining to image formation; an image forming section configured to form an image on the sheet based on image data indicated by an image formation instruction received by the reception section; an exit tray onto which the sheet is ejected after the image has been formed thereon by the image forming section; and an operation control section configured to control operation of the sheet feed section, the sheet conveyance section, and the image forming section, wherein when the reception section receives an instruction for duplex image formation that indicates the sheet feed cassette, the operation control section: controls the sheet feed section to feed one or more sheets from the sheet feed cassette; controls the image forming section to form images on respective first sides of the sheets based on image data of one group out of an even number page group and an odd number page group among image data indicated by the instruction received by the reception section; and controls the sheet conveyance section to eject the sheets onto the exit tray after the images have been formed on the first sides thereof by the image forming section, the reception section is configured to receive input from a user indicating whether the sheets ejected onto the exit tray after the images have been formed on the first sides thereof are new sheets having unused second sides or reused sheets having used second sides, and when the reception section receives input indicating that the sheets ejected onto the exit tray are the new sheets having the unused second sides and the operation control section determines that the sheets ejected onto the exit tray have been loaded onto the manual feed tray, the operation control section: controls the sheet feed section to feed the sheets loaded onto the manual feed tray; controls the image forming section to form images on the second sides of the sheets fed from the manual feed tray based on image data of the other group out of the even number page group and the odd number page group among the image data indicated by the instruction received by the reception section; and controls the sheet conveyance section to eject the sheets onto the exit tray after the images have been formed on the second sides thereof by the image forming section.
