Abstract

Disclosed is a photosensitive device for use in e1ectro~ statographic copying. The device comprises: a) an endless, arcuate substrate; and b) a thin conductive filament having a layer on its surface of a photoconductive insulating material wrapped in helical configuration around said substrate. The filament is connected to ground or to a suitable bias source,

Disclosed is a photosensitive device for use in e1ectro~

statographic copying. The device comprises:

a) an endless, arcuate substrate; and

b) a thin conductive filament having a layer on its
surface of a photoconductive insulating material wrapped
in helical configuration around said substrate. The
filament is connected to ground or to a suitable bias
source,

The device is illustrated by Fig. 1 in which substrate 10
has on its surface a monolayer of coated filament 12
wrapped around the substrate in helical configuration. The
coated filament comprises a core 14 of a conductive material
uniformly coated with a layer of photoconductive insulating
material 16. Normally, the coated filament is bonded to
the substrate by a thin layer of adhesive material 18, part
of which will tend to be extruded up into the spaces between
the coated filaments during fabrication of the gravure
member.

The embodiment illustrated in Fig. 1 is especially suitable
for use in the imaging method disclosed in U.S. Patent
3,801,315. In another embodiment, the filament layer is
overcoated with a thin layer of an insulating organic
resin to provide a device with a dielectric storage layer
on its exposed surface,
