Abstract
An image forming apparatus is provided with an image carrier that carries a visible image thereon, a transfer support element that conveys a sheet to which the visible image is transferred from the image carrier at a transfer nip portion, and a transfer member that applies a transfer bias to the transfer support element. The transfer member is in contact with an inner layer of the transfer support element at an edge of the transfer nip portion. The transfer member has a medium inherent volume resistance which is less than an inherent volume resistance of the inner layer of the transfer support element. Further, a plurality of transfer members may be provided, in which case the transfer member closest to the transfer nip portion has the medium inherent volume resistance.
