ABSTRACT:
In an image forming apparatus, during the course of recording, a cleaning roller is rotated together with an image carrier. The roller frictionally charges toner left on the image carrier after image transfer to the same polarity. A cleaning member electrostatically collects the charged toner. At the same time, a voltage is applied to the cleaning member by a voltage applying device in order to cause it to attract the charged toner, thereby cleaning the image carrier. Hence, even when the toner remaining on image carrier is charged partly to the positive polarity and partly to the negative polarity, the toner can be entirely transferred to the cleaning member by a simple construction.
