    摘要： An image forming apparatus includes a toner image supporting section and a medium transfer section. The toner image supporting section includes first and second toner image supporting member that support first and second toner images at first and second linear speeds, respectively. The medium transfer section transfers, onto a medium, the first and second toner images respectively supported by the first and second toner image supporting members, to thereby cause the first and second toner images to be superimposed on each other. The following conditional expression (1) is satisfied when the medium transfer section transfers the first and second toner images onto the medium, (Vd1−Vt1)/(Vt1>(Vd2−Vt2)/Vt2  (1) where Vd1 is the first linear speed, Vt1 is a first conveyance speed of the medium, Vd2 is the second linear speed, and Vt2 is a second conveyance speed of the medium.

    摘要： 3-D printers include a transfuse station having at least one roller on one side of an ITB supporting the ITB, and a transmission device on the same side of the ITB. A charge neutralizer is included on a second side of the intermediate transfer surface. The charge neutralizer outputs an opposite charge to neutralize existing static charge on a layer of the build material and the support material on the ITB, before the layer reaches the transfer station. Additionally, the intermediate transfer surface transfers the layer to a platen each time the platen contacts the second side of the intermediate transfer surface, at the transfer station, to successively form layers of the build material and the support material on the platen. Also, the transmission device outputs acoustic waves to cause the layer to move from the intermediate transfer surface to the platen, or to the layers on the platen.

    摘要： A transfer device includes a power supply control unit, a direct-current (DC) power supply, an alternating-current (AC) power supply, and a transfer unit. The power supply control unit controls a first control signal for controlling a DC voltage and a second control signal for controlling an AC voltage based on a condition relating to image formation. The DC power supply outputs the DC voltage based on the first control signal. The AC power supply selectively outputs, with a particular waveform, either of the DC voltage output from the DC power supply or a superimposed voltage obtained by superimposing the AC voltage determined based on the second control signal on the DC voltage output from the DC power supply. The transfer unit transfers a developer onto a sheet using a voltage output from the AC power supply.

    摘要： An image forming apparatus includes image carriers that carry toner images; an intermediate transfer body that is brought into contact with the image carriers to carry the images before transferring them to a recording material; first transfer devices that include first transfer members and form first-transfer electric fields for transferring the images on the image carriers to the intermediate transfer body; a second transfer device that includes a second transfer member and forms a second-transfer electric field for transferring the images transferred to the intermediate transfer body to the recording material; and an adjusting device that adjusts an electric field to be formed in a second transfer area to a cleaning electric field, which is of the same polarity as and a lower intensity than the second-transfer electric field, when the images on the intermediate transfer body passes through the second transfer area without a recording material passing therethrough.
