Transfer of Electrophotographic Latent Image (continued report)

Abstract

The authors have reported in the previous paper about some investigations concerning the transfer of electrostatic latent images. In the preceding experiment, a metal cylinder was used as one of the elecrtodes to perform the image transfer, but it was not suitable for studying the phenomenon quantitatively.
In the present article, additional results are given using another experimental arrangement.
Both the original and the image receiving matter are inserted between two flat electrodes, on which the bias voltage is imposed by a rotating switch.
The voltage pulse width is controlled by varying the effective width of contacting electrode of this switch.
Transfer characteristics are measured under various voltage imposing conditions using electrophotographic paper, plate, and resin coated paper as testing materials.
