ABSTRACT:
An electrographic reproduction apparatus, of the single-pass type, capable of producing simplex or duplex copies on a receiver sheet traveling in a continuous direction along a path. The reproduction apparatus comprises a first dielectric member movable along a first path, a portion of such first path being tangent to and on one side of the sheet travel path. Transferable images, corresponding to information to be reproduced, are sequentially formed on such first member. A second member is movable along a second path. One portion of such second path is tangent to the sheet travel path on the opposite side from the first path; and another portion of the second path, spaced from such one portion, is located to position the second member in image transfer relation to the first dielectric member. An electrostatic field, reversible in its effective direction, is utilized to transfer a transferable image from the first dielectric member to the second member at the portion of the second path where the first and second members are in image transfer relation, and transfer such image from the second member to one side of a receiver sheet traveling along its travel path at the location where the position of the first path is tangent to the sheet travel path; and for producing a duplex copy, a second image is transferred from the first dielectric member to the opposite side of such receiver sheet at the location where the portion of the first path is tangent to the sheet travel path.
