Abstract
A medium transporting apparatus includes a feeding roller that rotates to transport a medium along a transportation path, an electrode installed downstream of the feeding roller on the transportation path and having conductivity, and an electric charge detecting circuit that outputs a signal having a magnitude corresponding to an amount of an electric charge, which moves from the medium to the electrode after the medium being transported along the transportation path comes into contact with the electrode.
