Method For Rendering Imaging Member Substrates Non-Reflective
view source
US Patent:

54297150, Jul 4, 1995
Filed:

Nov 1, 1993
Appl. No.:

8/143709
Inventors:

Mark S. Thomas - Williamson NY
Phillip G. Perry - Webster NY
David J. Maty - Ontario NY
Richard J. Manzolati - Rochester NY
Gene W. O'Dell - Williamson NY
Assignee:

Xerox Corporation - Stamford CT
International Classification:

C23F 100
US Classification:

216103
Abstract:

A method of rendering nonreflective an imaging member substrate, preferably a photoreceptor substrate, involves etching the substrate with (a) an effective amount of an etching agent at a temperature sufficient to effect etching of the substrate, wherein the etching agent comprises (i) high purity deionized water, (ii) a mixture of high purity deionized water and a mild acid or (iii) a mixture of high purity deionized water and a base; or (b) a combination of the etching agent (a) and modulating ultrasonic energy. This method renders the substrate clean, spotless, and pristine, and provides it with uniform surface roughness.
