Abstract

A transfer unit includes a pair of guide and field stabilizer members disposed adjacent to a transfer member and along a conveying path for a transfer sheet. A voltage is applied to the stabilizer members which is of the same polarity as a bias voltage applied to the transfer member. It is assured that transfer sheet reliably contacts the pair of field stabilizer members as it passes therebetween.
