An image forming apparatus includes an image bearing member, discharging wires for discharging electricity to the image bearing member, a frictionally sliding device for reciprocating while frictionally sliding along the discharging wires, and a switch for changing the numbers of reciprocation of the frictionally sliding devices. With the apparatus, it is made possible for the apparatus to perform discharges uniformly from the very beginning when the discharge wires are used, and also, to perform image formation without unevenness due to the stains that may adhere to the wires by the repeated use thereof.
