Abstract
A paper feeding device of an embodiment includes a paper feed cassette, an alignment component, a fan, and a fan guiding duct component. A paper bundle in which a plurality of sheets of paper are stacked can be placed on the paper feed cassette. The alignment component can align the paper bundle placed on the paper feed cassette. The fan is connected to the alignment component. The fan can generate airflow. The fan guiding duct component is connected to the alignment component. The fan guiding duct component is positioned above the paper bundle placed on the paper feed cassette. The fan guiding duct component generates a negative pressure between the fan guiding duct component and an uppermost sheet of paper in the paper bundle due to the airflow from the fan.
