Electrostatic image transfer apparatus

摘要

An image transfer device includes: first and second rollers; and exit-side roller disposed downstream of the second roller; an endless transfer belt tensioned between the first roller and the exit-side roller with the second roller in between so that the part of the transfer belt between the first and second rollers can be kept in contact with a photoreceptor; a conductive, endless voltage supplying belt tensioned between the first and second rollers so as to come in contact with a wide area of the inside surface of the transfer belt. The first roller is applied with a predetermined voltage from a power source so that the voltage is supplied to the transfer range of the transfer belt via the voltage supplying belt. In this arrangement, when a sheet of paper is conveyed into the contact area between the transfer belt and the photoreceptor, a toner image formed on the photoreceptor is transferred to the fed sheet of paper.
