Abstract
A process for depositing particles within a softenable layer to form a migration imaging member wherein the layer is softened by heating, exposed in a first deposition zone to a high impingement rate of vapors of selenium or selenium alloy moving along in a line of sight path from a selenium or selenium alloy source to form a sub-surface monolayer of spherical particles comprising the selenium or selenium alloy, removed from the first deposition zone prior to a substantial dropoff in transmission optical density, exposed to a lower impingement rate of vapors of selenium or selenium alloy in a second deposition zone to increase the size of the spherical particles while maintaining a narrow particle size distribution and achieving a high surface packing density thereby increasing the transmission optical density of the imaging member, and thereafter removed from the second deposition zone prior to a substantial dropoff in transmission optical density.
