  • Publication number: 20140291915
    Abstract: An image forming apparatus includes a registration roller pair, which is arranged on a downstream side in a sheet feeding direction with respect to a nip portion of a sheet feeding roller and a separation roller, configured to cause a leading edge of a sheet, the sheet is conveyed while being nipped by the sheet feeding roller and the separation roller, to abut against the stopped registration roller pair to form warping in the sheet. And, a backup sheet is deformed toward a separation roller side by abutting against the sheet, which has been warped by abutting the leading edge of the sheet against the registration roller pair, from the separation roller side in a vicinity of the downstream side in the sheet feeding direction with respect to the nip portion.
