Abstract
An image forming apparatus having a refeeding unit for temporarily containing image-formed sheets as a horizontal pile and for refeeding the sheets for the second image forming operation. The refeeding unit can be pulled out from a body frame in the direction perpendicular to a sheet transporting direction. A setting position of the refeeding unit in the body frame can be adjusted to be parallel with the sheet transporting direction. The refeeding unit has an intermediate tray on which the sheets are piled, a refeeding roller which feeds the sheets piled on the intermediate tray from the most bottom sheet successively one by one, a sheet front end aligning member, a sheet rear end aligning member, a sheet side aligning member and a sheet pressing plate which, every time a sheet is transported to the intermediate tray and every time a sheet is refed from the intermediate tray, presses the sheet toward the refeeding roller.
