ABSTRACT:
An image forming apparatus includes a brush member arranged along a photosensitive member and arranged between a transfer roller means and a charger. The image forming apparatus further includes a first voltage supply for supplying a first voltage which is sufficient to attract residual toner remaining on the photosensitive member to the brush member during a first period when an exposed area that is to be exposed by the exposing means passes the brush member, the first period occurring before the exposed area reaches the exposing means, and a second voltage supply for supplying a second voltage which is sufficient to spit the attracted toner attracted in the brush member at the photosensitive member during at least a part of a second period when a non-exposed area that is on a different area of the photosensitive member from the exposed area passes the brush member, the second period occurring before the non-exposed area reaches the exposing means.
