Abstract: An image forming apparatus includes a sheet feed unit which feeds a sheet to an image forming unit forming an image on the sheet, a re-transport roller which reverses the sheet with a toner image fixed on the sheet and re-transports the sheet to the image forming unit, and a control unit which controls a sheet feed operation of the sheet feed unit for feeding the sheet. As the temperature of the re-transport roller sensed by the temperature sensing unit is decreased, the control unit retards the timing at which the sheet feed unit starts the sheet feed operation when a duplex image formation in which the image is formed on both sides of the sheet is performed after a one-side image formation is completed.

Abstract: 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.
