摘要： An image forming apparatus employs a non-magnetic developing agent and a magnetic developing agent which have been charged to opposite polarities to develop at least first and second latent images formed on an image carrier in response to image information, thus forming first and second developed images. The first and second developed images are charged to the same polarity as that of the magetic developing agent, prior to the transfer onto a transfer medium so as to provide a vivid transferred image.

摘要： A corona discharging device having a corona discharging electrode to which a high voltage is applied to produce corona discharge. The high voltage applied to the corona discharging electrode is provided by superposing an AC voltage to a DC voltage. The DC voltage and the AC voltage are determined such that the corona discharging current has only the polarity which is the same as that of the DC component voltage. The corona discharge is stabilized and hardly produces a non-uniform discharge.

摘要： This specification discloses a device for developing electrostatic latent images by the use of developer. The device includes a photosensitive medium bearing electrostatic latent images on the surface thereof to be developed, a container for containing therein magnetic carrier and toner, a permanent magnet fixedly mounted within the container, and a non-magnetic sleeve enclosing the magnet and rotatably mounted in the container for transporting the developer from the container to the latent image bearing surface. The permanent magnet has poles of identical polarity disposed adjacent to each other at positions opposed to the latent image bearing surface. Thus, development can be effected in the developing station by utilization of repelling magnetic fields produced by the poles of identical polarity.
