Abstract
A recording device includes: a voltage application unit that applies a voltage exceeding a first threshold value to a display medium; a photosensitive layer in which an impedance changes depending on an irradiated light; and a light irradiation unit that irradiates light of a first intensity that changes the impedance of the display medium at the approximately same time as when the voltage is applied by the voltage application unit and, and when the voltage is no longer applied by the voltage application unit, irradiates light that has a second intensity lower than the first intensity and that damps the residual voltage to the second threshold value or below within a length of time equal to or less than the third threshold value.
