Image forming apparatus with modified transfer brush

An image forming apparatus comprising:

• an image bearing member adapted to bear a toner image;
• a transfer belt that is movable;
• and
• a transfer device adapted to transfer the toner image from the image bearing member the transfer belt, the transfer device being positioned on the opposite side of the transfer belt from the image bearing member, the transfer device including a brush member having a plurality of conductive filaments arranged to contact the transfer belt,
• wherein the conductive filaments, among the plurality of conductive filaments of the brush member, which are located towards an upstream end of the brush member, with respect to a moving direction of the transfer belt, are bonded.
