Abstract
Abstract A xerographic binder layer which comprises inorganic photoconductive particles contained in an insulating, fused, inorganic glass matrix, the photoconductive particles are present in an amount from about 1 to 25 percent by volume of the binder layer, and in the form of a plurality of continuous paths through the thickness of the layer. The method of making and imaging the binder layer is also described.

Claim 6
Dependent Claim
42 words
The method of claim 1 in which the glass frit particles in the particulate mixture are present in a size distribution from about 0.1 to 70 microns and the photoconductor particles have a size distribution of from about 0.001 to 2.0 microns.
Claim 7
Dependent Claim
38 words
The method of claim 1 in which the glass frit particles in the mixture have a size distribution from about 1 to 10 microns aNd the photoconductor particles have a size distribution from about 0.001 to 1 micron.
Claim 8
Dependent Claim
28 words
The method of claim 8 in which the mean or average particle size of glass frit is at least five times greater than than of the photoconductor particles.
Claim 9
Dependent Claim
44 words
The method of claim 1 in which the photoconductor particles in the particulate mixture are present in an amount from about 3 to 15 percent by volume and the glass frit binder particles in an amount from about 85 to 97 percent by volume.
Claim 10
Dependent Claim
47 words
The method of claim 1 in which the particulate mixture of glass frit and photoconductor particles is formed as a slurry with a carrier liquid in which neither material is soluble, and which is evaporated to form a dried binder layer prior to fusing the glass particles.
Claim 11
Dependent Claim
13 words

Claim 12
Dependent Claim
26 words
The method of claim 1 in which the glass frit particles have a mean size at least 100 times greater than that of the photoconductive particles.
