Abstract
Abstract Apparatus for transferring developed latent electrostatic images from a support surface to a transfer member using electrostatic techniques. A corona generating device has a plurality of spacedapart brushes mounted such that the brushes force the transfer member into contact with the support surface. Energization of the corona generating device causes the developed image to be transferred to the transfer member.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
115 words
Apparatus for transferring a developed image formed on a support surface to a transfer member comprising: a support surface having a developed image formed thereon, a corona generating device located adjacent said support surface, means supported on said corona generating device for forcing a transfer member into contact with said support surface, means for introducing a transfer member between said support surface and said corona generating device whereby said transfer member is forced into contact with said support surface by said forcing means, and means for producing relative motion between said corona generating device and said support suRface, energization of said corona generating device causing said developed image to be transferred to said transfer member.
Claim 2
Dependent Claim
115 words
Apparatus for transferring a developed image formed on a support surface to a transfer member comprising: a support surface having a developed image formed thereon, a corona generating device located adjacent said support surface, means supported on said corona generating device for forcing a transfer member into contact with said support surface, means for introducing a transfer member between said support surface and said corona generating device whereby said transfer member is forced into contact with said support surface by said forcing means, and means for producing relative motion between said corona generating device and said support suRface, energization of said corona generating device causing said developed image to be transferred to said transfer member.
Claim 3
Dependent Claim
14 words
