Abstract

A print medium feeding apparatus includes an endless belt disposed to face stacked media and configured to rotate, the endless belt divided into sections having electrodes, respectively, fixed terminals configured to be in contact with two or more of the electrodes while the two or more of the electrodes are passing through a position facing the media as the electrodes are moved by rotation of the endless belt, a voltage applying unit connected to the fixed terminals and configured to apply voltage to the two or more of the electrodes that are in contact with the fixed terminals, a connection unit configured to make and break a connection between the voltage applying unit and at least one of the fixed terminals, and a switching unit configured to change a state of the connection of the connection unit in response to size of the media.
