Abstract
Official abstract text for this publication.
An image forming apparatus includes: a sheet feed unit that feeds a sheet to an image forming unit forming a toner image on the sheet; a fixing unit that fixes the toner image formed in the image forming unit to the sheet; and a control unit that controls the sheet feed unit, when starting duplex image formation for forming both sides of the sheet after an one-side image formation, the control unit retards a timing to cause the sheet feed unit to start the sheet feed operation as the number of sheet with an image formed on one side thereof in the one-side image formation is greater.
