Abstract

Aluminized MYLAR* brand polyester film, about 3 mils thick, is tested for acceptability as a substrate for a layered xerographic photoconductor. In this test, the initial few feet of a long jumbo roll of substrate is first coated with a known xerographic charge transport layer (CTL). This coated section is now charged, in the dark, to a high DC voltage. For example, a P-type CTL is charged negative. This charged area is now developed, using, for example, a magnetic brush developer, again in the dark. The now-toned area is visually inspected. If untoned areas, such as streaks, are noted, the jumbo roll is rejected for use in manufacture of a xerographic photoconductor. * Trademark of E. I. du Pont de Nemours & Co.
