Abstract

There is disclosed an apparatus which may comprise a transfer member and a photoconductor. The apparatus may be operable to apply a potential difference between the transfer member and the photoconductor and the photoconductor may be operable to transfer a layer of electrostatic printing material from the photoconductor to the transfer member at a transfer region under the action of the applied potential difference. According to the present disclosure, the apparatus may further comprise a humidity raising device which may be operable to raise the relative humidity of the transfer region above an ambient level. A printer and a method of facilitating transfer of electrostatic printing material are also disclosed.
