Abstract
An image forming apparatus includes a feeding unit for sequentially feeding a plurality of originals to an exposure plate, an exposure unit, which is movable along the exposure plate, for exposing the original on the exposure plate, an image forming unit for forming on a sheet an image on the original that is exposed by the exposure unit, and a control unit for providing either a first copying operation, in which the original is shifted by the feeding unit while the exposure unit is halted to perform copying, or a second copying operation, in which the exposure unit is shifted while the originals that are fed by the feeding unit are halted on the exposure plate. When the control unit executes a first mode in (e.g. copies>1) which the second copying operation is performed following the first copying operation, the feeding unit feeds the originals while maintaining a first constant distance between a leading end of a preceding original and a leading end of a succeeding original, and wherein, when the control unit executes a second mode (e.g. copies=1) in which only the first copying operation is performed, the feeding unit feeds the originals while maintaining a second constant distance between a trailing end of a preceding original and a leading end of a succeeding original.
