发明名称 Image forming apparatus and image forming method
摘要 There is provided an image forming apparatus that can suppress the formation of creases when forming images on both surfaces of a sheet and can greatly reduce the incidence of unprinted areas. The image forming apparatus has a sheet stacking section in which sheets are stacked, a sheet conveying section that conveys a sheet, an image forming section that forms an image on the sheet while the sheet is conveyed, a re-conveying section that again conveys the sheet with the image formed on a first surface thereof to the image forming section, and a sheet feeding section that feeds a sheet from the sheet stacking section or the re-conveying section to the image forming section. When a sheet is fed from the sheet stacking section for image formation on the first surface of the sheet by the image forming section, the sheet is fed at a first speed, and when a sheet is fed from the re-conveying section for image formation on a second surface of the sheet by the image forming section, the sheet is fed at a second speed that is slower than the first speed and is slower than the speed at which the sheet is conveyed by the sheet conveying section.
