摘要

1309649 Manifold imaging process XEROX CORP 15 April 1970 [18 April 1969] 17959/70 Heading G2H A manifold sandwich 209, 203, 207 is charged at 213, 215; imagewise exposed at 223; re-charged at 225, 227 with the same polarity and at least the same magnitude as the first charge; and then separated to form complementary images. The second charge is provided because the first charge tends to decay by the time the sandwich is separated.
