Abstract
A paper feeding apparatus includes a tray, an air blower, a floating detector, and a hardware processor. In the tray, a sheet of paper is loaded. The air blower blows air to the sheet loaded in the tray to float the sheet. The floating detector is provided above the sheet loaded in the tray and detects the floating of the sheet to a predetermined level. The hardware processor causes the air blower to blow the air and determines a basis weight of the sheet loaded in the tray from an air amount that has caused the floating detector to detect the floating of the sheet.
