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: In a printing device, the conveying mechanism has a first path from a accommodating unit to the printing position and a second path that conveys the sheet that has once passed through the printing position to the printing position in an inverted state. The controller controls the conveying mechanism to perform an automatic duplex print. Printing on the one side is executed by using the first path and printing on the another side is executed by using the second path. The another side printing error disables printing of an image, by using the second path, on the another side of the sheet, whose one side has already been printed. When the another side printing error occurs, the controller controls the conveying mechanism to convey, through the first path, a sheet and controlling the printing unit to print the image on the sheet based on the set of image data to be printed on the another side.
