In an electronic copier provided with a light-sensitive medium, a charging station, an exposure station, a developing station, a transfer station and a fixing unit, the charging station includes a plurality of contact charging elements in contact with the light-sensitive medium and a voltage supply means for applying voltages to the contact charging elements. A voltage continuously rising in a predetermined period of time is supplied from the voltage supply means to the contact charging elements with the rotation of light-sensitive medium, and the light-sensitive medium is thus uniformly charged.
