<P>PROBLEM TO BE SOLVED: To provide a charging device where a charging member may be efficiently cleaned. Ž<P>SOLUTION: An image forming apparatus includes: a plurality of charging members (electrode wire 33) which apply charging voltage between each charging member and corresponding charged body (photoreceptor drum 1); a plurality of cleaning members (a first pad 37 and second pad 38) which remove adherent matters by reciprocating in a contact state with each charging member and wait in a waiting position in a non-cleaning time; a plurality of detection means (detection switches SW1 to SW4) which detect by availability of electric connection whether or not each cleaning member is located in the waiting position; and a series circuit that connects the plurality of detection means in series, wherein when the cleaning members clean the charging members, an outward movement is started from a cleaning member on a side corresponding to one end of the series circuit, and a homeward movement is completed from a cleaning member on a side corresponding to the other end of the series circuit.
