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.
Claims8
A transfer unit for an electrophotographic copying machine including field stabilizer means disposed adjacent to a transfer member and having a voltage applied thereto which is of the same polarity as a bias voltage applied to the transfer member, the field stabilizer means comprising a first field stabilizer member having an extension which extends into a conveying path for a transfer sheet, the extension guiding the transfer sheet to pass along the conveying path while causing the sheet to bear smoothly against the extension, and a second field stabilizer member disposed adjacent to the first field stabilizer member and on the opposite side of the conveying path from the first member, the second member urging the transfer sheet into contact with the extension of the first member as the transfer sheet passes through the conveying path.
A transfer unit for an electrophotographic copying machine including field stabilizer means disposed adjacent to a transfer member, said field stabilizer means having a voltage applied thereto which is of the same polarity as a bias voltage applied to said transfer member, said transfer member having an input feed side and an output feed side, said field stabilizer means being disposed on said input feed side of said transfer member, said field stabilizer means comprising a first field stabilizer member having an extension which extends into a conveying path for a transfer sheet for guiding the transfer sheet to pass along the conveying path while causing the sheet to bear against said extension, and a second field stabilizer member disposed adjacent to said first field stabilizer member and on the opposite side of the conveying path from said first member, said second member urging said transfer sheet into contact with said extension of said first member as said transfer sheet passes through said conveying path.
