Abstract
This invention provides a process for electrographically imaging a plurality of substrates heretofore not usable in such a system. While prior art dielectric substrates could be used in the present process, the specific parameters outlined in this invention allows many more charge retentive surfaces or substrates to be used in electrostatic imaging. The process involves developing the latent electrostatic image before dissipation of the image charge which can be calculated by the inventive process for each substrate to be used.
