Abstract
In an electrophotographic copying apparatus a substantial saving of space is realized at the image-transfer-separation area by providing the transfer electrode with a shield having an open face opposite the photosensitive drum and an open end adjacent which a grounded separation roller is mounted. The separation roller acts as an end plate of the shield and receives a charge from the transfer electrode. The charged separation roller rotating at the same peripheral speed as the drum thereby attracts the transfer paper from the drum to the roller, thereby separating the paper from the drum.
