An image forming apparatus includes: a photosensitive member; a charging member configured to charge the photosensitive member at a photosensitive member charging position to form an electrostatic image on the photosensitive member; a developing device configured and positioned to develop the electrostatic image with toner to form a toner image; a transferring device configured to transfer the toner image to an image receiving member at a transfer position; a first brush, disposed at a position downstream of the transfer position and upstream of the photosensitive member charging position with respect to a rotational direction of the photosensitive member, configured to charge a residual toner on the photosensitive member at a toner charging position to collect the residual toner to the developing device and to be supplied with a charging bias having a polarity opposite to a regular charge polarity of the toner; and a second brush, disposed at a position downstream of the toner charging position and upstream of the photosensitive member charging position with respect to the rotational direction, configured to charge the residual toner on the photosensitive member and to be supplied with a charging bias having the same polarity as the regular charge polarity. The first brush has a fiber density smaller than that of the second brush. |
