Abstract
A sheet is fed to a registration roller pair by a separation-feeding unit formed by a sheet feeding roller and a separation portion, and is caused to abut a nip portion of the registration roller pair at rest to form a loop in the sheet. Then, when the registration roller pair rotates at a predetermined timing to convey the sheet, a pressurization plate is raised again to bring the sheet into press contact with the sheet feeding roller to thereby impart a conveyance force to the sheet, making it possible to feed the sheet reliably to the registration roller pair.
