Abstract: A transfer bias voltage supplier supplies, to a transfer member, a transfer bias voltage of a polarity opposite to the polarity of toner. The absolute value of transfer bias voltage to be supplied to the transfer member when a leading/trailing end of the sheet is passed through the nip portion is set smaller than when a toner image transfer region of the sheet is passed through the nip portion. A separation bias voltage supplier supplies, to a discharging electrode member, a separation bias voltage of a polarity opposite to the polarity of transfer bias voltage. The absolute value of separation bias voltage to be supplied to the discharging electrode member when the leading/trailing end of the sheet is passed through a discharging gap is set smaller than when the transfer region is passed through the discharging gap.

Abstract: A secondary transfer facing roller includes a roller part that has a through-hole penetrating in a rotary shaft line direction at a rotation center position, and a penetrating shaft member penetrating the through-hole of the roller part and spinning the roller part on a surface of the penetrating shaft member. Eccentric cams are fixed to both end regions that are not located in the roller part, so as to rotate integrally with the penetrating shaft member. A position regulating cam and an abutting roller form a gap between the intermediate transfer belt and the secondary transfer roller immediately before a transfer sheet enters a transfer nip part. While the gap is formed, current flows between the intermediate transfer belt and the secondary transfer roller via the position regulating cam and the abutting roller.

Abstract: A piezographic imaging process includes the use of a composite photoreceptor structure that includes a piezoactive layer that enables Xerographic imaging without corona charge/transfer subsystems. Flexure of the photoreceptor structure creates electric fields sufficient for the creation of developable latent electrostatic image patterns. Flexure of the photoreceptor structure following development generates an electric field for transfer of toner images onto paper.

Abstract: A magnetographic copier system in which images recorded on a magnetic tape are developed by toner with magnetic properties and where the toner particles are also electrostatically charged. A piece of paper is brought into contact with the tape at a toner transfer station and a first momentary electric field of the proper polarity and orientation is then used to transfer the developed toner images from the tape to paper. The paper and tape segments with the images are then separated and are moved away from the toner transfer station. An electrode external to the transfer station is then used to apply another electric field of the same polarity to the developed toner images on the paper to prevent the toner from being disturbed by the next occurrence of the first electric field for subsequent toner images being transferred to the paper.

Abstract: Apparatus for printing images on paper or other print medium by transferring toner on a magnetic tape onto the paper, using a voltage pulse applied between electrodes located respectively behind the tape and behind the paper. The electrode behind the tape is narrower than the tape, so that the opposite edge portions of the tape serve as insulators that prevent the formation of electric arcs between the electrodes. The voltage is applied in the form of a high voltage pulse on the order of 1500 volts lasting on the order of one millisecond, to transfer toner, and is followed by a sustained voltage on the order of 150 volts for preventing the toner particles from shifting position on the paper.
