    摘要: An image forming apparatus includes a controller and a transfer device including a power source to output a superimposed bias in which an AC voltage is superimposed on a DC voltage, a first electrode, a second electrode disposed opposite the first electrode with an image bearing member interposed therebetween to form a transfer electric field to transfer a toner image on the image bearing member to a recording medium. The controller including a CPU adjusts the transfer electric field and a transfer speed. One of the first electrode and the second electrode is connected to the power source, and the other is grounded. The controller adjusts the transfer speed such that in a case in which an oscillating electric field of the transfer electric field is strong, a maximum transfer speed is slower than the maximum transfer speed in a case in which the oscillating electric field is weak.

    摘要: Electric discharge between a photosensitive member and a charge retaining medium is ON/OFF controlled by changing the gas pressure between these two members, so that it is possible to effect image recording in a state where a DC voltage is applied. An electric charge which is opposite in polarity to an image forming charge is uniformly formed on the charge retaining medium in advance of the image exposure, and thereafter image exposure is carried out, thereby reducing the background potential at the unexposed region and increasing the contrast potential of the electrostatic latent image formed on the charge retaining medium. In addition, it is possible to increase the voltage distribution to the photosensitive member. As a result, it is possible to improve the photosensitivity of image exposure.

    摘要: Electric discharge between a photosensitive member and a charge retaining medium is ON/OFF controlled by changing the gas pressure between these two members, so that it is possible to effect image recording in a state where a DC voltage is applied. Accordingly, it is possible to effect image recording on the charge retaining medium without the need for precise control for obtaining a high-voltage pulse and without employing an optical shutter. In addition, an electric charge that is emitted by a field is attracted to the charge retaining medium and accumulated on the surface thereof, thereby forming an electrostatic latent image, and thus making it possible to attain image recording of extremely high resolution.
