Abstract:
An image forming apparatus, comprising:(a) a movable image bearing member;(b) an image forming device for forming an image on the image bearing member with an electrically charged developer having an additive, the additive having one component configured for being charged to a same polarity as the developer and a second component configured for being charged to a different polarity from the developer;(c) a transferring device for transferring the image from the image bearing member to a recording medium at a transfer station;(d) a cleaning device having a cleaning member which makes a contact with the image bearing member for cleaning the image bearing member at a cleaning station located on a downstream side of the transfer station with respect to a direction along which the image bearing member travels; and(e) a processing device mounted between the transfer station and the cleaning station for processing the additive that has not been transferred but remains on the image bearing member so that the one component which is charged to the same polarity as the developer on the image bearing member is retained thereon and the other component which is charged to the different polarity from the developer is removed therefrom.
