Abstract

Abstract A migration imaging system having a migration imaging member with a binder layer of softenable material wherein a mixture of electrically photosensitive and inert fusible particles is dispersed and an imaging process wherein the fusible particles are fused thereby fixing the migrated image of the two types of particles. The imaged member is used as a lithographic printing master.
