Image forming apparatus with modified transfer brush

摘要

The image forming apparatus includes an image bearing member adapted to bear a toner image, a transfer belt configured to be movable, and a transfer device positioned across the transfer belt from the image bearing member and adapted to transfer the toner image from the image bearing member to the transfer belt. The transfer device includes a brush member equipped with a plurality of conductive filaments to be put into contact with the belt, wherein the plurality of conductive filaments located at an upstream end with respect to a moving direction of the transfer belt is cut along an orthogonal direction intersecting the moving direction of the transfer belt at right angles or the conductive filaments located at an upstream end of the brush member along the moving direction of the transfer belt are bonded together.
