An apparatus for improved transfer of charged developing material to a substrate in an electrophotographic printing apparatus by applying an oscillatory bias voltage to the charged developing material. The printing apparatus includes a toner transfer system having an intermediate transfer belt and a transfer station having a transfer charging device. The intermediate transfer member is provided with a biasing voltage, generating oscillatory electric fields in the transfer nip. As a result, the portion of the developed i mage present in the transfer nip is subjected to repeated transfer and back-transfer forces, resulting in fluidization, whereby the developed image is more efficiently transferred. <IMAGE>
