Transfer system for electrostatic reproduction machine

Abstract From the Canadian patent

An improved transfer system for transferring a developed electrostatic image from a photoreceptor to a transfer member includes an electrically biased transfer roll and a transfer corona generating device. Preferably the, corona generating device is an ultra-high field device having an instantaneous turn-on time. The transfer member is first fed between the photoreceptor and the transfer roll whereby transfer is initiated and the transfer member is electrostatically tacked to the photoreceptor, and then the transfer member moves beneath the transfer corona generating device whereby transfer is completed. The transfer roll applies a first charge to the transfer member, and the transfer …
