Recording apparatus responsive to changing electrical resistance of transfer media |
摘要 |
An image transferring apparatus is provided which holds a print sheet in a nip between an image carrier and a transfer roller and supplies the current to the transfer roller to transfer a toner image formed on the image carrier to the print medium. The apparatus has conductive brushes disposed in contact with ends. of the transfer roller to form a bypass circuit. The bypass circuit is connected to ground through a resistor and introduce the part of the current supplied to the transfer roller in an image transferring operation, thereby avoiding formation of any print defects such as discharge-caused marks or toner stops.
