Abstract

Disclosed herein is an apparatus for the electrostatic transfer of an electrostatically adherent toner image from a curvilinear surface of an electrostatographic copier, This apparatus comprises a plurality of rollers arranged axially parallel to one another, a continuous web of corona pervious material supported on at least two of the axially parallel rollers and at least one corona discharge electrode positioned relative to the corona pervious web so as to permit the electrostatic tacking of the electro- statically adherent toner image from the curvilinear sur- face to a receiving sheet as said receiving sheet is transported by the curvilinear surface through the region of contact of the web and the curvilinear surface,

Disclosed herein is an apparatus for the electrostatic
transfer of an electrostatically adherent toner image from
a curvilinear surface of an electrostatographic copier,
This apparatus comprises a plurality of rollers arranged
axially parallel to one another, a continuous web of
corona pervious material supported on at least two of the
axially parallel rollers and at least one corona discharge
electrode positioned relative to the corona pervious web
so as to permit the electrostatic tacking of the electro-
statically adherent toner image from the curvilinear sur-
face to a receiving sheet as said receiving sheet is
transported by the curvilinear surface through the region
of contact of the web and the curvilinear surface,

The continuous web which is supported on the axially
parallel rollers comp~'isesmaterials having a bulk resis-
tivity of at least 10°ohm-cia and has a porosity of at
least 30 and preferably greater than 50%. This apparatus
also includes means for advancement of the corona pervious
web in registration with the movement of the curvilinear
surface and means for activation of the corona discharge
electrode in registration with the passage of the receiv-~
ing sheet through the region of contact of the web and the
curvilinear surface,

In the preferred embodiments of this inventio...
