Abstract

An image forming apparatus wherein a sheet can be easily separated from a photosensitive drum both when an image is formed on one surface of a sheet and when an image is formed on the other surface, the image forming apparatus including an image forming device for using a photosensitive member to form an image on a sheet that is guided and fed along a sheet feeding path leading from a sheet stacking device, an initial curling device, positioned along the sheet feeding path, for processing the sheet so that the sheet curls away from the photosensitive member when the sheet is moved past the photosensitive member, a sheet conveying path along which the sheet, on one surface of which an image has been formed by the image forming device, is guided to the sheet feeding path, a surface reversing device, positioned along the route of the sheet conveying path, for reversing the surfaces of the sheet, and a recurling device, for processing the sheet so that the widthwise ends of the sheet curl away from the photosensitive member when the sheet delivered along the sheet conveying path is moved past the photosensitive member.
