Abstract
A sheet conveying apparatus permits keeping predetermined sheet intervals, even when sheet conveyance is temporarily discontinued and then resumed, after resumption of conveyance. The sheet conveying apparatus has a first roller which feeds sheets at predetermined sheet intervals, and a second roller which conveys a plurality of sheet fed from the first roller. After temporarily discontinuing conveyance of the plurality of sheets, conveyance of the plurality of sheets is resumed by use of the first roller and the second roller. The variation in the sheet interval caused when temporarily discontinuing sheet conveyance is corrected upon resumption of sheet conveyance.
