Claim:
An image forming apparatus comprising: a sheet stacking section in which sheets are stacked, each having a first surface and a second surface; a sheet conveying section that has a belt-shaped sheet conveying member that conveys the sheets; an image forming section that forms an image on a sheet while the sheet is conveyed by said sheet conveying section; a re-conveying section that again conveys the sheet having an image formed on the first surface thereof by said image forming section to said image forming section; a sheet feeding section that feeds a sheet from one of said sheet stacking section and said re-conveying section to said sheet conveying section; wherein the sheet is conveyed while it is held between said sheet conveying section and said sheet feeding section; an attraction section that holds the sheet on said conveying member by a predetermined attraction force; and a controller that controls the image forming apparatus; wherein said controller provides control such that the predetermined attraction force is set to a smaller value when the sheet is fed from said reconveying section to form an image on the second surface of the sheet than a value when the sheet is fed from said sheet stacking section to form an image on the first surface of the sheet.
