PROBLEM TO BE SOLVED: To provide an electrophotographic recording device that secures high cleaning efficiency for a long period. SOLUTION: The electrophotographic recording device includes a bias cleaning device provided with: a transfer unit which transfers a toner image formed on a photoreceptor to a transfer material; the conductive cleaning member which is applied with a voltage for removing a toner remaining on the photoreceptor after the transfser; and a recovery roller which is applied with a higher voltage than the conductive cleaning member for recovering a toner sticking on the conductive cleaning member. The higher voltage applied to the recovery roller is a bias voltage generated by superposing an AC voltage on a DC voltage having the opposite polarity from the toner. COPYRIGHT: (C)2010,JPO&INPIT |
