A sheet-material automatic feeding device individually separates and feeds sheets of a sheet material mounted on a tray. The device includes a sheet-material-leading-end detection sensor for detecting the leading end of the sheet material mounted on the tray, and a sheet-material prefeeding roller for feeding the sheet material mounted on the tray to a sheet-material separation/feeding unit provided at a position downstream from the sheet-material prefeeding roller. When the sheet-material-leading-end detection sensor has detected the leading end of the sheet material mounted on the tray, the sheet-material prefeeding roller is mounted on and presses a leading-end portion of the sheet material mounted on the tray.
