ABSTRACT:
A a sheet supplying apparatus includes a sheet holding member adapted to hold a plurality of sheets and having a regulating wall for regulating movement of the sheets in a sheet supplying direction, a sucker member for absorbing with a vacuum force an uppermost sheet among the sheets held by the sheet holding member, and a pressure reducer for reducing pressure in the sucker. In addition, a driver drives the sucker member to convey the sheet absorbed by the vacuum, a height detector detects a height position of the uppermost sheet, and a sheet urging member urges the sheets in a sheet stacking direction and moves the sheet toward the regulating wall. The sheet member urges means urging the uppermost sheet with predetermined pressure on the basis of the detected height position.
