Electrophotographic process |
摘要 |
An electrophotographic duplicating process suitable for high humidity conditions utilizes a magnetic brush developing device having an electrically conductive development electrode with an electrically insulating coating thereon in conjunction with a developer. The developer consists of toners with a volume resistivity higher than 1013 OMEGA xcm. and magnetic carriers with a volume resistivity of about 105 to 108 OMEGA xcm and has a toner concentration varying from about 7% to about 13% by weight. Once formed, an electrostatic charge latent image is repeatedly developed and transferred to an image receiving member to form at least twenty duplicated copies.
