摘要： A method and apparatus for electrostatically transferring a toner image from a toner image bearing member (TIBM) to a receiver sheet is disclosed. A receiver sheet is moved within a nip defined between a transfer roller having a resistive outer layer and a toner image bearing member supporting a toner image. To provide for transfer, there is applied an electrical bias to the resistive layer from a conductive member located beneath the resistive layer and in electrical contact with the resistive layer. There are also applied to an outer surface of the resistive layer a first contact voltage to establish an post-nip electrical voltage distribution to a post-nip region of the transfer roller that is immediately downstream of an in-nip region. The post-nip electrical voltage distribution is accomplished by having the first contact voltage be applied at first points on the outer layer of the transfer roller, the first points being within or proximate the post-nip region. There is also applied to the resistive outer layer a second contact voltage to establish an electrical voltage distribution to a pre-nip region of the transfer roller immediately up-stream of the in-nip region. This pre-nip electrical voltage distribution is accomplished by having the contact voltage be applied at second points on the outer layer of the transfer roller, the second points being within or proximate the pre-nip region. The resistivity of the outer layer, the voltage provided to the conductive member, the voltage bias to the TIBM, and the first and second contact voltages establish an in-nip electrical field or voltage suitable for transfer of the toner image to a receiver sheet and for suppression or reduction of pre-nip and post-nip ionization.

摘要： A device for handling corona charger wires in order to facilitate the placement of wires within the housing of the corona charger. The corona wire handling device includes a substantially rectangular frame, the frame having opposed long side members and opposed short side members. The long side members of the rectangular frame are readily separable from the short side members thereof. A mechanism, associated with the rectangular frame, is provided for supporting an intermediate portion of at least one corona wire on the frame. Further, a mechanism is provided for controlling tension on the corona wire induced by the corona wire intermediate support mechanism. Accordingly, when the rectangular frame is associated with the corona charger for placement of a corona wire operatively therein and the tension control mechanism is activated, tension increase in the corona wire induced by insertion of the corona wire in the corona charger is controlled to balance wire tension in order to prevent corona wire damage or breakage. Thereafter, the long side members of the rectangular frame are separated from the short side members to enable removal of excess portions of the rectangular frame and the wire supporting mechanism.

摘要： The contrast of an electrographic image or a region of interest of an electrographic image having low contrast is enhanced by developing the electrographic image with toner using a development electrode which is biased to a potential which has a value near the average potential of the image but outside of the range of values of potential corresponding to image features selected for enhancement. The voltage potential of the electrographic image is measured to determine the average potential in the region of interest. The development electrode bias is set at a potential near the average potential but outside of the range of potentials corresponding to the image features selected for enhancement in the region of interest of the image. When developed with toner, the toner image has enhanced contrast. If the image is a xeroradiographic image, diagnostic capability of low contrast regions can be enhanced.

摘要： Xeroprinting masters are formed by first forming a toner mask. The mask is used to expose a xeroprinting master material exhibiting persistent conductivity in response to a given wavelength and intensity of radiation. The toner mask can be formed and transferred to the xeroprinting material without fusing. After exposure the masking toner can be cleaned off providing a planographic master. Multicolor images are formed by forming two or more masking images, and transferring them to two or more master surfaces. After irradiation and cleaning each master surface is used as a xeroprinting master for a particular color in a multicolor duplicating system.

This pre-nip electrical voltage distribution is accomplished by having the contact voltage be applied at second points on the outer layer of the transfer roller, the second points being within or proximate the pre-nip region. Because of the resistivity of the outer layer, the pre-nip and post-nip voltage distributions establish an in-nip electrical field suitable for transfer of the toner image to a receiver sheet.
